###############################################################################

# United States

# From Paul Eggert (1999-03-31):
# Howse writes (pp 121-125) that time zones were invented by
# Professor Charles Ferdinand Dowd (1825-1904),
# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
# His pamphlet ``A System of National Time for Railroads'' (1870)
# was the result of his proposals at the Convention of Railroad Trunk Lines
# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
# and the most of the country soon followed suit.

# From Paul Eggert (2005-04-16):
# That 1883 transition occurred at 12:00 new time, not at 12:00 old time.
# See p 46 of David Prerau, Seize the daylight, Thunder's Mouth Press (2005).

# From Paul Eggert (2006-03-22):
# A good source for time zone historical data in the US is
# Thomas G. Shanks, The American Atlas (5th edition),
# San Diego: ACS Publications, Inc. (1991).
# Make sure you have the errata sheet; the book is somewhat useless without it.
# It is the source for most of the pre-1991 US entries below.

# From Paul Eggert (2001-03-06):
# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
# in his whimsical essay ``An Economical Project for Diminishing the Cost
# of Light'' published in the Journal de Paris (1784-04-26).
# Not everyone is happy with the results:
#
#	I don't really care how time is reckoned so long as there is some
#	agreement about it, but I object to being told that I am saving
#	daylight when my reason tells me that I am doing nothing of the kind.
#	I even object to the implication that I am wasting something
#	valuable if I stay in bed after the sun has risen.  As an admirer
#	of moonlight I resent the bossy insistence of those who want to
#	reduce my time for enjoying it.  At the back of the Daylight Saving
#	scheme I detect the bony, blue-fingered hand of Puritanism, eager
#	to push people into bed earlier, and get them up earlier, to make
#	them healthy, wealthy and wise in spite of themselves.
#
#	-- Robertson Davies, The diary of Samuel Marchbanks,
#	   Clarke, Irwin (1947), XIX, Sunday
#
# For more about the first ten years of DST in the United States, see
# Robert Garland's <a href="http://www.clpgh.org/exhibit/dst.html">
# Ten years of daylight saving from the Pittsburgh standpoint
# (Carnegie Library of Pittsburgh, 1927)</a>.
#
# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
# However, DST was imposed by the Standard Time Act of 1918, which
# was the first nationwide legal time standard, and apparently
# time was just called "Standard Time" or "Daylight Saving Time".

# From Arthur David Olson:
# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
# See, for example, the front page of the Saturday, 1974-10-26
# and Sunday, 1974-10-27 editions of the Washington Post.

# From Arthur David Olson:
# Before the Uniform Time Act of 1966 took effect in 1967, observance of
# Daylight Saving Time in the US was by local option, except during wartime.

# From Arthur David Olson (2000-09-25):
# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
# In the introduction, Oboler spoke of "Eastern Peace Time."
# An AltaVista search turned up
# <a href="http://rowayton.org/rhs/hstaug45.html">:
# "When the time is announced over the radio now, it is 'Eastern Peace
# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
# </a> (August 1945) by way of confirmation.

# From Joseph Gallant citing
# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
# to switch to London for Attlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
# London which were to precede Mr. Attlee's speech.

# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout.  From
# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
#
# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
# Any announcement from Asia would reach St. John's New York newsroom on a
# wire service teletype machine, which had prescribed signals for major news.
# Associated Press, for example, would ring five bells before spewing out
# typed copy of an important story, and 10 bells for news "of transcendental
# importance."
#
# On Aug. 14, stalling while talking steadily into the NBC networks' open
# microphone, St. John heard five bells and waited only to hear a sixth bell,
# before announcing confidently: "Ladies and gentlemen, World War II is over.
# The Japanese have agreed to our surrender terms."
#
# He had scored a 20-second scoop on other broadcasters.

# From Arthur David Olson (2005-08-22):
# Paul has been careful to use the "US" rules only in those locations
# that are part of the United States; this reflects the real scope of
# U.S. government action.  So even though the "US" rules have changed
# in the latest release, other countries won't be affected.

# From Arthur David Olson, 2005-12-19
# We generate the files specified below to guard against old files with
# obsolete information being left in the time zone binary directory.
# We limit the list to names that have appeared in previous versions of
# this time zone package.
# We do these as separate Zones rather than as Links to avoid problems if
# a particular place changes whether it observes DST.
# We put these specifications here in the northamerica file both to
# increase the chances that they'll actually get compiled and to
# avoid the need to duplicate the US rules in another file.

# ...Alaska's timezone lines were redrawn in 1983 to give only 2 tz.
#    The YST zone now covers nearly all of the state, AHST just part

#	central standard time
#	mountain standard time
#	Pacific standard time
#	Alaska standard time
#	Hawaii-Aleutian standard time
#	Samoa standard time
# The law doesn't give abbreviations.
#
# From Paul Eggert (2000-01-08), following a heads-up from Rives McDow:

# From Dave Cantor (2004-11-02):
# Early this summer I had the occasion to visit the Mount Washington
# Observatory weather station atop (of course!) Mount Washington [, NH]....
# One of the staff members said that the station was on Eastern Standard Time
# and didn't change their clocks for Daylight Saving ... so that their
# reports will always have times which are 5 hours behind UTC.

# From Paul Eggert (2005-08-26):
# According to today's Huntsville Times
# <http://www.al.com/news/huntsvilletimes/index.ssf?/base/news/1125047783228320.xml&coll=1>
# a few towns on Alabama's "eastern border with Georgia, such as Phenix City
# in Russell County, Lanett in Chambers County and some towns in Lee County,
# set their watches and clocks on Eastern time."  It quotes H.H. "Bubba"
# Roberts, city administrator in Phenix City. as saying "We are in the Central
# time zone, but we do go by the Eastern time zone because so many people work
# in Columbus."

# Alaska
# AK%sT is the modern abbreviation for -9:00 per USNO.
#
# From Paul Eggert (2001-05-30):
# Howse writes that Alaska switched from the Julian to the Gregorian calendar,
# and from east-of-GMT to west-of-GMT days, when the US bought it from Russia.
# This was on 1867-10-18, a Friday; the previous day was 1867-10-06 Julian,
# also a Friday.  Include only the time zone part of this transition,
# ignoring the switch from Julian to Gregorian, since we can't represent
# the Julian calendar.
#
# As far as we know, none of the exact locations mentioned below were
# permanently inhabited in 1867 by anyone using either calendar.
# (Yakutat was colonized by the Russians in 1799, but the settlement
# was destroyed in 1805 by a Yakutat-kon war party.)  However, there
# were nearby inhabitants in some cases and for our purposes perhaps
# it's best to simply use the official transition.

# and another part (e.g. Akiak) made the same switch five weeks later.
#
# From David Flater (2004-11-09):
# In e-mail, 2004-11-02, Ray Hudson, historian/liaison to the Unalaska
# Historic Preservation Commission, provided this information, which
# suggests that Unalaska deviated from statutory time from early 1967
# possibly until 1983:
#
#  Minutes of the Unalaska City Council Meeting, January 10, 1967:
#  "Except for St. Paul and Akutan, Unalaska is the only important
#  location not on Alaska Standard Time.  The following resolution was
#  made by William Robinson and seconded by Henry Swanson:  Be it
#  resolved that the City of Unalaska hereby goes to Alaska Standard
#  Time as of midnight Friday, January 13, 1967 (1 A.M. Saturday,

#  three votes for and one against."

# DST was observed for one day in 1933;
# standard time was changed by half an hour in 1947;
# it's always standard as of 1986.

# Now we turn to US areas that have diverged from the consensus since 1970.

# Arizona mostly uses MST.

# From Paul Eggert (2002-10-20):
#
# The information in the rest of this paragraph is derived from the
# <a href="http://www.dlapr.lib.az.us/links/daylight.htm">
# Daylight Saving Time web page (2002-01-23)</a> maintained by the
# Arizona State Library, Archives and Public Records.
# Between 1944-01-01 and 1944-04-01 the State of Arizona used standard
# time, but by federal law railroads, airlines, bus lines, military
# personnel, and some engaged in interstate commerce continued to
# observe war (i.e., daylight saving) time.  The 1944-03-17 Phoenix
# Gazette says that was the date the law changed, and that 04-01 was
# the date the state's clocks would change.  In 1945 the State of
# Arizona used standard time all year, again with exceptions only as
# mandated by federal law.  Arizona observed DST in 1967, but Arizona
# Laws 1968, ch. 183 (effective 1968-03-21) repealed DST.
#
# Shanks says the 1944 experiment came to an end on 1944-03-17.
# Go with the Arizona State Library instead.

# What time is it in Indiana?

#   Vandenburgh, and Warrick counties have been like America/Chicago.

# - Dearborn and Ohio counties have been like America/New_York.

# - Clark, Floyd, and Harrison counties have been like
#   America/Kentucky/Louisville.
#
# - Crawford, Daviess, Dubois, Knox, Martin, Perry, Pike, Pulaski, Starke,

#
# Shanks partitioned Indiana into 345 regions, each with its own time history,
# and wrote ``Even newspaper reports present contradictory information.''
# Those Hoosiers!  Such a flighty and changeable people!
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Other than Indianapolis, the Indiana place names are so nondescript

# From Paul Eggert (2006-01-20):
# It says "DOT is relocating the time zone boundary in Indiana to move Starke,
# Pulaski, Knox, Daviess, Martin, Pike, Dubois, and Perry Counties from the
# Eastern Time Zone to the Central Time Zone.... The effective date of
# this rule is 2:OO a.m. EST Sunday, April 2, 2006, which is the
# changeover date from standard time to Daylight Saving Time."
# Strictly speaking, this means the affected counties will change their
# clocks twice that night, but this obviously is in error.  The intent
# is that 01:59:59 EST be followed by 02:00:00 CDT.

# From Gwillim Law (2007-02-10):
# The Associated Press has been reporting that Pulaski County, Indiana is
# going to switch from Central to Eastern Time on March 11, 2007....

# Wayne County, Kentucky
#
# From

# Lake Cumberland LIFE
# </a> (1999-01-29) via WKYM-101.7:
# Clinton County has joined Wayne County in asking the DoT to change from
# the Central to the Eastern time zone....  The Wayne County government made
# the same request in December.  And while Russell County officials have not
# taken action, the majority of respondents to a poll conducted there in
# August indicated they would like to change to "fast time" also.
# The three Lake Cumberland counties are the farthest east of any U.S.
# location in the Central time zone.
#
# From Rich Wales (2000-08-29):
# After prolonged debate, and despite continuing deep differences of opinion,
# Wayne County (central Kentucky) is switching from Central (-0600) to Eastern
# (-0500) time.  They won't "fall back" this year.  See Sara Shipley,
# The difference an hour makes, Nando Times (2000-08-29 15:33 -0400).
#
# From Paul Eggert (2001-07-16):
# The final rule was published in the
# <a href="http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=2000_register&docid=fr17au00-22">

# From Rives McDow (2000-08-30):
# Here ... are all the changes in the US since 1985.
# Kearny County, KS (put all of county on central;
#	previously split between MST and CST) ... 1990-10
# Starke County, IN (from CST to EST) ... 1991-10
# Oliver County, ND (from MST to CST) ... 1992-10
# West Wendover, NV (from PST TO MST) ... 1999-10
# Wayne County, KY (from CST to EST) ... 2000-10
#
# From Paul Eggert (2001-07-17):
# We don't know where the line used to be within Kearny County, KS,
# so omit that change for now.
# See America/Indiana/Knox for the Starke County, IN change.
# See America/North_Dakota/Center for the Oliver County, ND change.
# West Wendover, NV officially switched from Pacific to mountain time on
# 1999-10-31.  See the
# <a href="http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=1999_register&docid=fr21oc99-15">
# Federal Register 64, 203 (1999-10-21), page 56705-56707.
# </a>
# However, the Federal Register says that West Wendover already operated
# on mountain time, and the rule merely made this official;
# hence a separate tz entry is not needed.

# Michigan
#
# From Bob Devine (1988-01-28):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1999-03-31):
# Shanks writes that Michigan started using standard time on 1885-09-18,
# but Howse writes (pp 124-125, referring to Popular Astronomy, 1901-01)
# that Detroit kept
#
#	local time until 1900 when the City Council decreed that clocks should
#	be put back twenty-eight minutes to Central Standard Time.  Half the
#	city obeyed, half refused.  After considerable debate, the decision
#	was rescinded and the city reverted to Sun time.  A derisive offer to
#	erect a sundial in front of the city hall was referred to the
#	Committee on Sewers.  Then, in 1905, Central time was adopted
#	by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# From Paul Eggert (2001-03-06):
# Garland (1927) writes ``Cleveland and Detroit advanced their clocks
# one hour in 1914.''  This change is not in Shanks.  We have no more
# info, so omit this for now.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# A good source for time zone historical data outside the U.S. is
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
#
# Gwillim Law writes that a good source

# Quebec

# From Paul Eggert (2006-07-09):

# like Montreal.

# From Paul Eggert (2006-06-27):
# Matthews and Vincent (1998) also write that Quebec east of the -63
# meridian is supposed to observe AST, but residents as far east as
# Natashquan use EST/EDT, and residents east of Natashquan use AST.
# In "Official time in Quebec" the Quebec department of justice writes in
# http://www.justice.gouv.qc.ca/english/publications/generale/temps-regl-1-a.htm
# that "The residents of the Municipality of the
# Cote-Nord-du-Golfe-Saint-Laurent and the municipalities of Saint-Augustin,
# Bonne-Esperance and Blanc-Sablon apply the Official Time Act as it is
# written and use Atlantic standard time all year round. The same applies to
# the residents of the Native facilities along the lower North Shore."
# <http://www.assnat.qc.ca/eng/37legislature2/Projets-loi/Publics/06-a002.htm>
# says this common practice was codified into law as of 2007.
# For lack of better info, guess this practice began around 1970, contra to
# Shanks & Pottenger who have this region observing AST/ADT.

# Ontario

# From Paul Eggert (2006-07-09):
# Shanks & Pottenger write that since 1970 most of Ontario has been like
# Toronto.
# Thunder Bay skipped DST in 1973.
# Many smaller locales did not observe peacetime DST until 1974;
# Nipigon (EST) and Rainy River (CST) are the largest that we know of.
# Far west Ontario is like Winnipeg; far east Quebec is like Halifax.

# From Mark Brader (2003-07-26):
# [According to the Toronto Star] Orillia, Ontario, adopted DST
# effective Saturday, 1912-06-22, 22:00; the article mentions that
# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
# have already done so.  In Orillia DST was to run until Saturday,
# 1912-08-31 (no time mentioned), but it was met with considerable
# hostility from certain segments of the public, and was revoked after
# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
# presumably that should be -07-06.  (1912-06-19, -07-12; also letters
# earlier in June).
#
# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).

# From Paul Eggert (1997-10-17):
# Mark Brader writes that an article in the 1997-10-14 Toronto Star
# says that Atikokan, Ontario currently does not observe DST,
# but will vote on 11-10 whether to use EST/EDT.
# He also writes that the
# <a href="http://www.gov.on.ca/MBS/english/publications/statregs/conttext.html">
# Ontario Time Act (1990, Chapter T.9)
# </a>
# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
# Officially Atikokan is therefore on CST/CDT, and most likely this report
# concerns a non-official time observed as a matter of local practice.
#
# From Paul Eggert (2000-10-02):
# Matthews and Vincent (1998) write that Atikokan, Pickle Lake, and
# New Osnaburgh observe CST all year, that Big Trout Lake observes
# CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in
# violation of the official Ontario rules.
#
# From Paul Eggert (2006-07-09):
# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to

# savings time in 1916, Fort William and Port Arthur, having done so

# Manitoba

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# Saskatchewan

# From Mark Brader (2003-07-26):
# The first actual adoption of DST in Canada was at the municipal
# level.  As the [Toronto] Star put it (1912-06-07), "While people
# elsewhere have long been talking of legislation to save daylight,
# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
# presumably late evening, as below), and would run until "the end of
# the summer".  The discrepancy between municipal time and railroad
# time was noted.

# From Paul Eggert (2003-07-27):
# Willett (1914-03) notes that DST "has been in operation ... in the
# City of Moose Jaw, Saskatchewan, for one year."

# From Paul Eggert (2006-03-22):
# Shanks & Pottenger say that since 1970 this region has mostly been as Regina.
# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
# Other western towns (e.g. Lloydminster) are like Edmonton.
# Matthews and Vincent (1998) write that Denare Beach and Creighton
# are like Winnipeg, in violation of Saskatchewan law.

# From W. Jones (1992-11-06):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other.  In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.

# From Chris Walton (2006-06-26):
# The Saskatchewan time act which was last updated in 1996 is about 30 pages
# long and rather painful to read.

# Northwest Territories, Nunavut, Yukon

# From Paul Eggert (2006-03-22):
# Dawson switched to PST in 1973.  Inuvik switched to MST in 1979.
# Mathew Englander (1996-10-07) gives the following refs:
#	* 1967. Paragraph 28(34)(g) of the Interpretation Act, S.C. 1967-68,
#	c. 7 defines Yukon standard time as UTC-9.  This is still valid;
#	see Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1).
#	* C.O. 1973/214 switched Yukon to PST on 1973-10-28 00:00.
#	* O.I.C. 1980/02 established DST.
#	* O.I.C. 1987/056 changed DST to Apr firstSun 2:00 to Oct lastSun 2:00.
# Shanks & Pottenger say Yukon's 1973-10-28 switch was at 2:00; go
# with Englander.
# From Chris Walton (2006-06-26):
# Here is a link to the old daylight saving portion of the interpretation
# act which was last updated in 1987:
# http://www.gov.yk.ca/legislation/regs/oic1987_056.pdf

# From Rives McDow (1999-09-04):

# Nunavut moves to single time zone Oct. 31
# </a>
#
# From Antoine Leca (1999-09-06):
# We then need to create a new timezone for the Kitikmeot region of Nunavut
# to differentiate it from the Yellowknife region.

# From Paul Eggert (1999-09-20):
# <a href="http://www.nunavut.com/basicfacts/english/basicfacts_1territory.html">
# Basic Facts: The New Territory
# </a> (1999) reports that Pangnirtung operates on eastern time,
# and that Coral Harbour does not observe DST.  We don't know when
# Pangnirtung switched to eastern time; we'll guess 1995.

# From Rives McDow (1999-11-08):
# On October 31, when the rest of Nunavut went to Central time,
# Pangnirtung wobbled.  Here is the result of their wobble:
#
# The following businesses and organizations in Pangnirtung use Central Time:
#
#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
#	Eastern Arctic National Parks, A & D Specialist
#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator
#
# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not
# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,
# so it appears that the situation will last at least that long.
# The Nunavut Intergovernmental Affairs hopes that they will "come to
# their senses", but the locals evidently don't see any problem with
# the current state of affairs.

# From Michaela Rodrigue, writing in the
# <a href="http://www.nunatsiaq.com/archives/nunavut991130/nvt91119_17.html">
# Nunatsiaq News (1999-11-19)</a>:
# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
# central - or Nunavut time - for government offices, and eastern time
# for municipal offices and schools....  Igloolik [was similar but then]
# made the switch to central time on Saturday, Nov. 6.

# From Paul Eggert (2000-10-02):
# Matthews and Vincent (1998) say the following, but we lack histories
# for these potential new Zones.
#
# The Canadian Forces station at Alert uses Eastern Time while the
# handful of residents at the Eureka weather station [in the Central
# zone] skip daylight savings.  Baffin Island, which is crossed by the
# Central, Eastern and Atlantic Time zones only uses Eastern Time.
# Gjoa Haven, Taloyoak and Pelly Bay all use Mountain instead of
# Central Time and Southampton Island [in the Central zone] is not
# required to use daylight savings.

# From
# <a href="http://www.nunatsiaq.com/archives/nunavut001130/nvt21110_02.html">
# Nunavut now has two time zones
# </a> (2000-11-10):
# The Nunavut government would allow its employees in Kugluktuk and
# Cambridge Bay to operate on central time year-round, putting them
# one hour behind the rest of Nunavut for six months during the winter.
# At the end of October the two communities had rebelled against
# Nunavut's unified time zone, refusing to shift to eastern time with
# the rest of the territory for the winter.  Cambridge Bay remained on
# central time, while Kugluktuk, even farther west, reverted to
# mountain time, which they had used before the advent of Nunavut's
# unified time zone in 1999.
#
# From Rives McDow (2001-01-20), quoting the Nunavut government:
# The preceding decision came into effect at midnight, Saturday Nov 4, 2000.

# From Paul Eggert (2000-12-04):
# Let's just keep track of the official times for now.

# From Rives McDow (2001-03-07):
# The premier of Nunavut has issued a ministerial statement advising
# that effective 2001-04-01, the territory of Nunavut will revert
# back to three time zones (mountain, central, and eastern).  Of the
# cities in Nunavut, Coral Harbor is the only one that I know of that
# has said it will not observe dst, staying on EST year round.  I'm
# checking for more info, and will get back to you if I come up with
# more.
# [Also see <http://www.nunatsiaq.com/nunavut/nvt10309_06.html> (2001-03-09).]

# From Gwillim Law (2005-05-21):
# According to maps at
# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SWE.jpg
# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SSE.jpg
# (both dated 2003), and
# http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp
# (from a 1998 Canadian Geographic article), the de facto and de jure time
# for Southampton Island (at the north end of Hudson Bay) is UTC-5 all year
# round.  Using Google, it's easy to find other websites that confirm this.
# I wasn't able to find how far back this time regimen goes, but since it
# predates the creation of Nunavut, it probably goes back many years....
# The Inuktitut name of Coral Harbour is Sallit, but it's rarely used.
#
# From Paul Eggert (2005-07-26):
# For lack of better information, assume that Southampton Island observed
# daylight saving only during wartime.

# From Chris Walton (2007-03-01):
# ... the community of Resolute (located on Cornwallis Island in
# Nunavut) moved from Central Time to Eastern Time last November.
# Basically the community did not change its clocks at the end of
# daylight saving....
# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html

# From Chris Walton (2007-03-14):
# Today I phoned the "hamlet office" to find out what Resolute was doing with
# its clocks.
#
# The individual that answered the phone confirmed that the clocks did not
# move at the end of daylight saving on October 29/2006.  He also told me that
# the clocks did not move this past weekend (March 11/2007)....

# From Chris Walton (2008-11-13):
# ...the residents of Resolute believe that they are changing "time zones"
# twice a year.  In winter months, local time is qualified with "Eastern
# Time" which is really "Eastern Standard Time (UTC-5)".  In summer
# months, local time is qualified with "Central Time" which is really
# "Central Daylight Time (UTC-5)"...

# Mexico

# From Paul Eggert (2001-03-05):
# The Investigation and Analysis Service of the
# Mexican Library of Congress (MLoC) has published a
# <a href="http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/">
# history of Mexican local time (in Spanish)
# </a>.
#
# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC.
# (In all cases we go with the MLoC.)
# S&P report that Baja was at -8:00 in 1922/1923.
# S&P say the 1930 transition in Baja was 1930-11-16.
# S&P report no DST during summer 1931.
# S&P report a transition at 1932-03-30 23:00, not 1932-04-01.

# From Gwillim Law (2001-02-20):
# There are some other discrepancies between the Decrees page and the
# tz database.  I think they can best be explained by supposing that
# the researchers who prepared the Decrees page failed to find some of
# the relevant documents.

# From Alan Perry (1996-02-15):
# A guy from our Mexico subsidiary finally found the Presidential Decree
# outlining the timezone changes in Mexico.
#
# ------------- Begin Forwarded Message -------------
#
# I finally got my hands on the Official Presidential Decree that sets up the
# rules for the DST changes. The rules are:
#
# 1. The country is divided in 3 timezones:
#    - Baja California Norte (the Mexico/BajaNorte TZ)
#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
#    - The rest of the country (the Mexico/General TZ)
#
# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
#    at 2:00 AM, the times in each zone are as follows:
#    BajaNorte: GMT+7
#    BajaSur:   GMT+6
#    General:   GMT+5
#
# 3. The rest of the year, the times are as follows:
#    BajaNorte: GMT+8
#    BajaSur:   GMT+7
#    General:   GMT+6
#
# The Decree was published in Mexico's Official Newspaper on January 4th.
#
# -------------- End Forwarded Message --------------
# From Paul Eggert (1996-06-12):
# For an English translation of the decree, see
# <a href="http://mexico-travel.com/extra/timezone_eng.html">
# ``Diario Oficial: Time Zone Changeover'' (1996-01-04).
# </a>

# From Rives McDow (1998-10-08):
# The State of Quintana Roo has reverted back to central STD and DST times
# (i.e. UTC -0600 and -0500 as of 1998-08-02).

# From Rives McDow (2000-01-10):
# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
# zone 5 hours from the International Date Line, and will not observe daylight
# savings time so as to stay on the same time zone as the southern part of
# Arizona year round.

# From Jesper Norgaard, translating
# <http://www.reforma.com/nacional/articulo/064327/> (2001-01-17):
# In Oaxaca, the 55.000 teachers from the Section 22 of the National
# Syndicate of Education Workers, refuse to apply daylight saving each
# year, so that the more than 10,000 schools work at normal hour the
# whole year.

# From Gwillim Law (2001-01-19):
# <http://www.reforma.com/negocios_y_dinero/articulo/064481/> ... says
# (translated):...
# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced
# that Summer Time will be reduced from seven to five months, starting
# this year....
# <http://www.publico.com.mx/scripts/texto3.asp?action=pagina&pag=21&pos=p&secc=naci&date=01/17/2001>
# [translated], says "summer time will ... take effect on the first Sunday
# in May, and end on the last Sunday of September.

# From Arthur David Olson (2001-01-25):
# The 2001-01-24 traditional Washington Post contained the page one
# story "Timely Issue Divides Mexicans."...
# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
# Mexico City and its 20 million residents on a different time than
# the rest of the country..." In particular, Lopez Obrador would abolish
# observation of Daylight Saving Time.

# <a href="http://www.conae.gob.mx/ahorro/decretohorver2001.html#decre">
# Official statute published by the Energy Department
# </a> (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
# and Sonora with no DST.  This was reported by Jesper Norgaard (2001-02-03).

# From Paul Eggert (2001-03-03):
#
# <a href="http://www.latimes.com/news/nation/20010303/t000018766.html">
# James F. Smith writes in today's LA Times
# </a>
# * Sonora will continue to observe standard time.
# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
#   the Federal District will not adopt DST.
# * 4 of 16 district leaders announced they'll ignore the decree.
# * The decree does not affect federal-controlled facilities including
#   the airport, banks, hospitals, and schools.
#
# For now we'll assume that the Federal District will bow to federal rules.

# From Jesper Norgaard (2001-04-01):
# I found some references to the Mexican application of daylight
# saving, which modifies what I had already sent you, stating earlier
# that a number of northern Mexican states would go on daylight
# saving. The modification reverts this to only cover Baja California
# (Norte), while all other states (except Sonora, who has no daylight
# saving all year) will follow the original decree of president
# Vicente Fox, starting daylight saving May 6, 2001 and ending
# September 30, 2001.

# Palabra <http://palabra.infosel.com/010331/primera/ppri3101.pdf> (2001-03-31)

# From Reuters (2001-09-04):
# Mexico's Supreme Court on Tuesday declared that daylight savings was
# unconstitutional in Mexico City, creating the possibility the
# capital will be in a different time zone from the rest of the nation
# next year....  The Supreme Court's ruling takes effect at 2:00
# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
# standard time. "This is so residents of the Federal District are not
# subject to unexpected time changes," a statement from the court said.

# From Jesper Norgaard Welen (2002-03-12):
# ... consulting my local grocery store(!) and my coworkers, they all insisted
# that a new decision had been made to reinstate US style DST in Mexico....
# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
# confirms this.  Sonora as usual is the only state where DST is not applied.

# From Steffen Thorsen (2009-12-28):
#
# Steffen Thorsen wrote:
# > Mexico's House of Representatives has approved a proposal for northern
# > Mexico's border cities to share the same daylight saving schedule as

# Now this has passed both the Congress and the Senate, so starting from
# 2010, some border regions will be the same:

# From Paul Eggert (2006-03-22):
# Formerly there was an America/Ensenada zone, which differed from
# America/Tijuana only in that it did not observe DST from 1976
# through 1995.  This was as per Shanks (1999).  But Shanks & Pottenger say
# Ensenada did not observe DST from 1948 through 1975.  Guy Harris reports
# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
# DST-observance was a town-by-town matter back then.  This concerns
# data after 1970 so most likely there should be at least one Zone
# other than America/Tijuana for Baja, but it's not clear yet what its
# name or contents should be.

# Next year, however, clocks in the US will go forward on the second Sunday
# in March, until the first Sunday in November.  And, after the Time Zone
# (Seasonal Variation) Bill 2006 was passed in the House of Assembly on

# Cuba

# From Arthur David Olson (1999-03-29):
# The 1999-03-28 exhibition baseball game held in Havana, Cuba, between
# the Cuban National Team and the Baltimore Orioles was carried live on
# the Orioles Radio Network, including affiliate WTOP in Washington, DC.
# During the game, play-by-play announcer Jim Hunter noted that
# "We'll be losing two hours of sleep...Cuba switched to Daylight Saving
# Time today."  (The "two hour" remark referred to losing one hour of
# sleep on 1999-03-28--when the announcers were in Cuba as it switched
# to DST--and one more hour on 1999-04-04--when the announcers will have
# returned to Baltimore, which switches on that date.)

# From Evert van der Veer via Steffen Thorsen (2004-10-28):
# Cuba is not going back to standard time this year.
# From Paul Eggert (2006-03-22):
# http://www.granma.cu/ingles/2004/septiembre/juev30/41medid-i.html
# says that it's due to a problem at the Antonio Guiteras
# thermoelectric plant, and says "This October there will be no return
# to normal hours (after daylight saving time)".
# For now, let's assume that it's a temporary measure.

# From Carlos A. Carnero Delgado (2005-11-12):
# This year (just like in 2004-2005) there's no change in time zone
# adjustment in Cuba.  We will stay in daylight saving time:
# http://www.granma.cu/espanol/2005/noviembre/mier9/horario.html

# From Jesper Norgaard Welen (2006-10-21):
# An article in GRANMA INTERNACIONAL claims that Cuba will end
# the 3 years of permanent DST next weekend, see
# http://www.granma.cu/ingles/2006/octubre/lun16/43horario.html
# "On Saturday night, October 28 going into Sunday, October 29, at 01:00,
# watches should be set back one hour -- going back to 00:00 hours -- returning
# to the normal schedule....

# From Paul Eggert (2007-03-02):
# http://www.granma.cubaweb.cu/english/news/art89.html, dated yesterday,
# says Cuban clocks will advance at midnight on March 10.
# For lack of better information, assume Cuba will use US rules,
# except that it switches at midnight standard time as usual.
#
# From Steffen Thorsen (2007-10-25):
# Carlos Alberto Fonseca Arauz informed me that Cuba will end DST one week 
# earlier - on the last Sunday of October, just like in 2006.
# 
# He supplied these references:

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
# </a>
#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.

# From Alexander Krivenyshev (2009-03-04)
# According to the Radio Reloj - Cuba will start Daylight Saving Time on
# midnight between Saturday, March 07, 2009 and Sunday, March 08, 2009-
# not on midnight March 14 / March 15 as previously thought.

# </a>
# this morning; when it was 10:05 a. m. here in Bethesda, Maryland the
# the time was announced as "diez cinco"--the same time as here, indicating
# that has indeed switched to DST. Assume second Sunday from 2009 forward.

# From Rives McDow (2000-12-01):

# Dominican Republic will be reverting to 8 hours from the International Date

# Haiti
# From Gwillim Law (2005-04-15):
# Risto O. Nykanen wrote me that Haiti is now on DST.
# I searched for confirmation, and I found a
# <a href="http://www.haitianconsulate.org/time.doc"> press release
# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
# </a>.  Translated from French, it says:
#
#  "The Prime Minister's Communication Office notifies the public in general
#   and the press in particular that, following a decision of the Interior
#   Ministry and the Territorial Collectivities [I suppose that means the
#   provinces], Haiti will move to Eastern Daylight Time in the night from next
#   Saturday the 2nd to Sunday the 3rd.
#
#  "Consequently, the Prime Minister's Communication Office wishes to inform
#   the population that the country's clocks will be set forward one hour
#   starting at midnight.  This provision will hold until the last Saturday in
#   October 2005.
#
#  "Port-au-Prince, March 31, 2005"
#
# From Steffen Thorsen (2006-04-04):
# I have been informed by users that Haiti observes DST this year like
# last year, so the current "only" rule for 2005 might be changed to a
# "max" rule or to last until 2006. (Who knows if they will observe DST
# next year or if they will extend their DST like US/Canada next year).
#
# I have found this article about it (in French):
# http://www.haitipressnetwork.com/news.cfm?articleID=7612
#
# The reason seems to be an energy crisis.

# From Stephen Colebourne (2007-02-22):
# Some IATA info: Haiti won't be having DST in 2007.

# From Paul Eggert (2005-05-01):
# The decree doesn't say anything about daylight saving, but for now let's
# assume that it is daylight saving....
#
# From Gwillim Law (2005-04-21):
# The Associated Press story on the time change, which can be found at
# http://www.lapalmainteractivo.com/guias/content/gen/ap/America_Latina/AMC_GEN_NICARAGUA_HORA.html
# and elsewhere, says (fifth paragraph, translated from Spanish):  "The last
# time that a change of clocks was applied to save energy was in the year 2000
# during the Arnoldo Aleman administration."...
# The northamerica file says that Nicaragua has been on UTC-6 continuously
# since December 1998.  I wasn't able to find any details of Nicaraguan time
# changes in 2000.  Perhaps a note could be added to the northamerica file, to
# the effect that we have indirect evidence that DST was observed in 2000.
#
# From Jesper Norgaard Welen (2005-11-02):
# Nicaragua left DST the 2005-10-02 at 00:00 (local time).

# http://www.elnuevodiario.com.ni/2006/05/01/nacionales/18410
# (my informal translation)
# By order of the president of the republic, Enrique Bolanos, Nicaragua
# advanced by sixty minutes their official time, yesterday at 2 in the
# morning, and will stay that way until 30.th. of september.
#
# From Jesper Norgaard Welen (2006-09-30):

# This file is in the public domain, so clarified as of

# also includes Central America and the Caribbean

# This data is by no means authoritative; if you think you know better,
# go ahead and edit the file (and please send any changes to
# tz@@iana.org for general use in the future).

# From Paul Eggert (1999-03-22):
# A reliable and entertaining source about time zones is
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

###############################################################################

# United States

# From Paul Eggert (1999-03-31):
# Howse writes (pp 121-125) that time zones were invented by
# Professor Charles Ferdinand Dowd (1825-1904),
# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
# His pamphlet ``A System of National Time for Railroads'' (1870)
# was the result of his proposals at the Convention of Railroad Trunk Lines
# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
# and the most of the country soon followed suit.

# From Paul Eggert (2005-04-16):
# That 1883 transition occurred at 12:00 new time, not at 12:00 old time.
# See p 46 of David Prerau, Seize the daylight, Thunder's Mouth Press (2005).

# From Paul Eggert (2006-03-22):
# A good source for time zone historical data in the US is
# Thomas G. Shanks, The American Atlas (5th edition),
# San Diego: ACS Publications, Inc. (1991).
# Make sure you have the errata sheet; the book is somewhat useless without it.
# It is the source for most of the pre-1991 US entries below.

# From Paul Eggert (2001-03-06):
# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
# in his whimsical essay ``An Economical Project for Diminishing the Cost
# of Light'' published in the Journal de Paris (1784-04-26).
# Not everyone is happy with the results:
#
#	I don't really care how time is reckoned so long as there is some
#	agreement about it, but I object to being told that I am saving
#	daylight when my reason tells me that I am doing nothing of the kind.
#	I even object to the implication that I am wasting something
#	valuable if I stay in bed after the sun has risen.  As an admirer
#	of moonlight I resent the bossy insistence of those who want to
#	reduce my time for enjoying it.  At the back of the Daylight Saving
#	scheme I detect the bony, blue-fingered hand of Puritanism, eager
#	to push people into bed earlier, and get them up earlier, to make
#	them healthy, wealthy and wise in spite of themselves.
#
#	-- Robertson Davies, The diary of Samuel Marchbanks,
#	   Clarke, Irwin (1947), XIX, Sunday
#
# For more about the first ten years of DST in the United States, see
# Robert Garland's <a href="http://www.clpgh.org/exhibit/dst.html">
# Ten years of daylight saving from the Pittsburgh standpoint
# (Carnegie Library of Pittsburgh, 1927)</a>.
#
# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
# However, DST was imposed by the Standard Time Act of 1918, which
# was the first nationwide legal time standard, and apparently
# time was just called "Standard Time" or "Daylight Saving Time".

# From Arthur David Olson:
# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
# See, for example, the front page of the Saturday, 1974-10-26
# and Sunday, 1974-10-27 editions of the Washington Post.

# From Arthur David Olson:
# Before the Uniform Time Act of 1966 took effect in 1967, observance of
# Daylight Saving Time in the US was by local option, except during wartime.

# From Arthur David Olson (2000-09-25):
# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
# In the introduction, Oboler spoke of "Eastern Peace Time."
# An AltaVista search turned up
# <a href="http://rowayton.org/rhs/hstaug45.html">:
# "When the time is announced over the radio now, it is 'Eastern Peace
# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
# </a> (August 1945) by way of confirmation.

# From Joseph Gallant citing
# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
# to switch to London for Attlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
# London which were to precede Mr. Attlee's speech.

# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout.  From
# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
#
# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
# Any announcement from Asia would reach St. John's New York newsroom on a
# wire service teletype machine, which had prescribed signals for major news.
# Associated Press, for example, would ring five bells before spewing out
# typed copy of an important story, and 10 bells for news "of transcendental
# importance."
#
# On Aug. 14, stalling while talking steadily into the NBC networks' open
# microphone, St. John heard five bells and waited only to hear a sixth bell,
# before announcing confidently: "Ladies and gentlemen, World War II is over.
# The Japanese have agreed to our surrender terms."
#
# He had scored a 20-second scoop on other broadcasters.

# From Arthur David Olson (2005-08-22):
# Paul has been careful to use the "US" rules only in those locations
# that are part of the United States; this reflects the real scope of
# U.S. government action.  So even though the "US" rules have changed
# in the latest release, other countries won't be affected.

# From Arthur David Olson, 2005-12-19
# We generate the files specified below to guard against old files with
# obsolete information being left in the time zone binary directory.
# We limit the list to names that have appeared in previous versions of
# this time zone package.
# We do these as separate Zones rather than as Links to avoid problems if
# a particular place changes whether it observes DST.
# We put these specifications here in the northamerica file both to
# increase the chances that they'll actually get compiled and to
# avoid the need to duplicate the US rules in another file.

# ...Alaska's timezone lines were redrawn in 1983 to give only 2 tz.
#    The YST zone now covers nearly all of the state, AHST just part

# From Paul Eggert (1995-12-19):

#	central standard time
#	mountain standard time
#	Pacific standard time
#	Alaska standard time
#	Hawaii-Aleutian standard time
#	Samoa standard time
# The law doesn't give abbreviations.
#
# From Paul Eggert (2000-01-08), following a heads-up from Rives McDow:
# Public law 106-564 (2000-12-23) introduced the abbreviation

# From Dave Cantor (2004-11-02):
# Early this summer I had the occasion to visit the Mount Washington
# Observatory weather station atop (of course!) Mount Washington [, NH]....
# One of the staff members said that the station was on Eastern Standard Time
# and didn't change their clocks for Daylight Saving ... so that their

# From Paul Eggert (2005-08-26):
# According to today's Huntsville Times
# <http://www.al.com/news/huntsvilletimes/index.ssf?/base/news/1125047783228320.xml&coll=1>
# a few towns on Alabama's "eastern border with Georgia, such as Phenix City

# set their watches and clocks on Eastern time."  It quotes H.H. "Bubba"
# Roberts, city administrator in Phenix City. as saying "We are in the Central
# time zone, but we do go by the Eastern time zone because so many people work
# in Columbus."

# Alaska
# AK%sT is the modern abbreviation for -9:00 per USNO.
#
# From Paul Eggert (2001-05-30):
# Howse writes that Alaska switched from the Julian to the Gregorian calendar,
# and from east-of-GMT to west-of-GMT days, when the US bought it from Russia.
# This was on 1867-10-18, a Friday; the previous day was 1867-10-06 Julian,
# also a Friday.  Include only the time zone part of this transition,
# ignoring the switch from Julian to Gregorian, since we can't represent
# the Julian calendar.
#
# As far as we know, none of the exact locations mentioned below were
# permanently inhabited in 1867 by anyone using either calendar.
# (Yakutat was colonized by the Russians in 1799, but the settlement
# was destroyed in 1805 by a Yakutat-kon war party.)  However, there
# were nearby inhabitants in some cases and for our purposes perhaps
# it's best to simply use the official transition.

# The author lives in Alaska and many of the references listed are only
# available to Alaskan residents.

# From Arthur David Olson (2011-02-01):
# Here's database-relevant material from the 2001 "Alaska History" article:
#
# On September 20 [1979]...DOT...officials decreed that on April 27,
# 1980, Juneau and other nearby communities would move to Yukon Time.
# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
# Pacific Time.
#
# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
# Department's September 1979 decision. Juneau and other communities in
# northern Southeast reverted to Pacific Time on October 26.
#
# On October 28 [1983]...the Metlakatla Indian Community Council voted
# unanimously to keep the reservation on Pacific Time.
#
# According to DOT official Joanne Petrie, Indian reservations are not
# bound to follow time zones imposed by neighboring jurisdictions.
#
# (The last is consistent with how the database now handles the Navajo
# Nation.)

# From Arthur David Olson (2011-02-09):
# I just spoke by phone with a staff member at the Metlakatla Indian
# Community office (using contact information available at
# <a href="http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla">
# http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla
# </a>).
# It's shortly after 1:00 here on the east coast of the United States;
# the staffer said it was shortly after 10:00 there. When I asked whether
# that meant they were on Pacific time, they said no--they were on their
# own time. I asked about daylight saving; they said it wasn't used. I
# did not inquire about practices in the past.

# From Arthur David Olson (2011-08-17):
# For lack of better information, assume that Metlakatla's
# abandonment of use of daylight saving resulted from the 1983 vote.

# and another part (e.g. Akiak) made the same switch five weeks later.
#
# From David Flater (2004-11-09):
# In e-mail, 2004-11-02, Ray Hudson, historian/liaison to the Unalaska
# Historic Preservation Commission, provided this information, which
# suggests that Unalaska deviated from statutory time from early 1967
# possibly until 1983:
#
#  Minutes of the Unalaska City Council Meeting, January 10, 1967:
#  "Except for St. Paul and Akutan, Unalaska is the only important
#  location not on Alaska Standard Time.  The following resolution was
#  made by William Robinson and seconded by Henry Swanson:  Be it
#  resolved that the City of Unalaska hereby goes to Alaska Standard
#  Time as of midnight Friday, January 13, 1967 (1 A.M. Saturday,
#  January 14, Alaska Standard Time.)  This resolution was passed with
#  three votes for and one against."

# From Arthur David Olson (2010-12-09):
# "Hawaiian Time" by Robert C. Schmitt and Doak C. Cox appears on pages 207-225

# and indicates that standard time was adopted effective noon, January
# 13, 1896 (page 218), that in "1933, the Legislature decreed daylight
# saving for the period between the last Sunday of each April and the
# last Sunday of each September, but less than a month later repealed the
# act," (page 220), that year-round daylight saving time was in effect
# from 1942-02-09 to 1945-09-30 (page 221, with no time of day given for
# when clocks changed) and that clocks were changed by 30 minutes
# effective the second Sunday of June, 1947 (page 219, with no time of
# day given for when clocks changed). A footnote for the 1933 changes
# cites Session Laws of Hawaii 1933, "Act. 90 (approved 26 Apr. 1933)
# and Act 163 (approved 21 May 1933)."

# From Arthur David Olson (2011-01-19):
# The following is from "Laws of the Territory of Hawaii Passed by the
# Seventeenth Legislature: Regular Session 1933," available (as of
# 2011-01-19) at American University's Pence Law Library. Page 85: "Act
# 90...At 2 o'clock ante meridian of the last Sunday in April of each
# year, the standard time of this Territory shall be advanced one
# hour...This Act shall take effect upon its approval. Approved this 26th
# day of April, A. D. 1933. LAWRENCE M JUDD, Governor of the Territory of

# hereby repealed...This Act shall take effect upon its approval, upon
# which date the standard time of this Territory shall be restored to
# that existing immediately prior to the taking effect of said Act 90.

# Now we turn to US areas that have diverged from the consensus since 1970.

# <a href="http://www.dlapr.lib.az.us/links/daylight.htm">
# Daylight Saving Time web page (2002-01-23)</a> maintained by the
# Arizona State Library, Archives and Public Records.
# Between 1944-01-01 and 1944-04-01 the State of Arizona used standard
# time, but by federal law railroads, airlines, bus lines, military
# personnel, and some engaged in interstate commerce continued to
# observe war (i.e., daylight saving) time.  The 1944-03-17 Phoenix
# Gazette says that was the date the law changed, and that 04-01 was
# the date the state's clocks would change.  In 1945 the State of
# Arizona used standard time all year, again with exceptions only as
# mandated by federal law.  Arizona observed DST in 1967, but Arizona
# Laws 1968, ch. 183 (effective 1968-03-21) repealed DST.
#
# Shanks says the 1944 experiment came to an end on 1944-03-17.
# Go with the Arizona State Library instead.

# What time is it in Indiana?

#
# From Paul Eggert (2007-08-17):
# Since 1970, most of Indiana has been like America/Indiana/Indianapolis,
# with the following exceptions:
#
# - Gibson, Jasper, Lake, LaPorte, Newton, Porter, Posey, Spencer,
#   Vandenburgh, and Warrick counties have been like America/Chicago.
#
# - Dearborn and Ohio counties have been like America/New_York.
#
# - Clark, Floyd, and Harrison counties have been like
#   America/Kentucky/Louisville.
#
# - Crawford, Daviess, Dubois, Knox, Martin, Perry, Pike, Pulaski, Starke,
#   and Switzerland counties have their own time zone histories as noted below.
#
# Shanks partitioned Indiana into 345 regions, each with its own time history,
# and wrote ``Even newspaper reports present contradictory information.''
# Those Hoosiers!  Such a flighty and changeable people!
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Other than Indianapolis, the Indiana place names are so nondescript

# Wayne County, Kentucky
#
# From
# <a href="http://www.lake-cumberland.com/life/archive/news990129time.shtml">
# Lake Cumberland LIFE
# </a> (1999-01-29) via WKYM-101.7:
# Clinton County has joined Wayne County in asking the DoT to change from
# the Central to the Eastern time zone....  The Wayne County government made
# the same request in December.  And while Russell County officials have not
# taken action, the majority of respondents to a poll conducted there in
# August indicated they would like to change to "fast time" also.
# The three Lake Cumberland counties are the farthest east of any U.S.
# location in the Central time zone.
#
# From Rich Wales (2000-08-29):
# After prolonged debate, and despite continuing deep differences of opinion,
# Wayne County (central Kentucky) is switching from Central (-0600) to Eastern
# (-0500) time.  They won't "fall back" this year.  See Sara Shipley,
# The difference an hour makes, Nando Times (2000-08-29 15:33 -0400).
#
# From Paul Eggert (2001-07-16):
# The final rule was published in the
# <a href="http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=2000_register&docid=fr17au00-22">

# From Rives McDow (2000-08-30):
# Here ... are all the changes in the US since 1985.
# Kearny County, KS (put all of county on central;
#	previously split between MST and CST) ... 1990-10
# Starke County, IN (from CST to EST) ... 1991-10
# Oliver County, ND (from MST to CST) ... 1992-10
# West Wendover, NV (from PST TO MST) ... 1999-10
# Wayne County, KY (from CST to EST) ... 2000-10
#
# From Paul Eggert (2001-07-17):
# We don't know where the line used to be within Kearny County, KS,
# so omit that change for now.
# See America/Indiana/Knox for the Starke County, IN change.
# See America/North_Dakota/Center for the Oliver County, ND change.
# West Wendover, NV officially switched from Pacific to mountain time on
# 1999-10-31.  See the
# <a href="http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=1999_register&docid=fr21oc99-15">
# Federal Register 64, 203 (1999-10-21), page 56705-56707.
# </a>
# However, the Federal Register says that West Wendover already operated
# on mountain time, and the rule merely made this official;
# hence a separate tz entry is not needed.

# Michigan
#
# From Bob Devine (1988-01-28):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1999-03-31):
# Shanks writes that Michigan started using standard time on 1885-09-18,
# but Howse writes (pp 124-125, referring to Popular Astronomy, 1901-01)
# that Detroit kept
#
#	local time until 1900 when the City Council decreed that clocks should
#	be put back twenty-eight minutes to Central Standard Time.  Half the
#	city obeyed, half refused.  After considerable debate, the decision
#	was rescinded and the city reverted to Sun time.  A derisive offer to
#	erect a sundial in front of the city hall was referred to the
#	Committee on Sewers.  Then, in 1905, Central time was adopted
#	by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# From Paul Eggert (2001-03-06):
# Garland (1927) writes ``Cleveland and Detroit advanced their clocks
# one hour in 1914.''  This change is not in Shanks.  We have no more
# info, so omit this for now.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# From Paul Eggert (2006-03-22):

# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
#
# Gwillim Law writes that a good source

# H. David Matthews and Mary Vincent's map
# <a href="http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp">
# "It's about TIME", _Canadian Geographic_ (September-October 1998)

# information about standard and daylight saving time zones in Canada.
# </a> (updated periodically).
# Its unofficial information is often taken from Matthews and Vincent.

# From Paul Eggert (2006-06-27):
# For now, assume all of DST-observing Canada will fall into line with the
# new US DST rules,

# From Chris Walton (2011-12-01)
# In the first of Tammy Hardwick's articles

# she quotes the Friday November 1/1918 edition of the Creston Review.
# The quote includes these two statements:
# 'Sunday the CPR went back to the old system of time...'
# '... The daylight saving scheme was dropped all over Canada at the same time,'
# These statements refer to a transition from daylight time to standard time
# that occurred nationally on Sunday October 27/1918.  This transition was
# also documented in the Saturday October 26/1918 edition of the Toronto Star.

# In light of that evidence, we alter the date from the earlier believed
# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day
# than Thursday) in all Canadian rulesets.

# Quebec

# From Paul Eggert (2006-07-09):

# Ontario

# From Paul Eggert (2006-07-09):
# Shanks & Pottenger write that since 1970 most of Ontario has been like
# Toronto.
# Thunder Bay skipped DST in 1973.
# Many smaller locales did not observe peacetime DST until 1974;
# Nipigon (EST) and Rainy River (CST) are the largest that we know of.
# Far west Ontario is like Winnipeg; far east Quebec is like Halifax.

# From Mark Brader (2003-07-26):
# [According to the Toronto Star] Orillia, Ontario, adopted DST
# effective Saturday, 1912-06-22, 22:00; the article mentions that
# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
# have already done so.  In Orillia DST was to run until Saturday,
# 1912-08-31 (no time mentioned), but it was met with considerable
# hostility from certain segments of the public, and was revoked after
# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
# presumably that should be -07-06.  (1912-06-19, -07-12; also letters
# earlier in June).
#
# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).

# From Paul Eggert (1997-10-17):
# Mark Brader writes that an article in the 1997-10-14 Toronto Star
# says that Atikokan, Ontario currently does not observe DST,
# but will vote on 11-10 whether to use EST/EDT.
# He also writes that the
# <a href="http://www.gov.on.ca/MBS/english/publications/statregs/conttext.html">
# Ontario Time Act (1990, Chapter T.9)
# </a>
# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
# Officially Atikokan is therefore on CST/CDT, and most likely this report
# concerns a non-official time observed as a matter of local practice.
#
# From Paul Eggert (2000-10-02):
# Matthews and Vincent (1998) write that Atikokan, Pickle Lake, and
# New Osnaburgh observe CST all year, that Big Trout Lake observes
# CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in
# violation of the official Ontario rules.
#
# From Paul Eggert (2006-07-09):
# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# From Mark Brader (2010-03-06):
#
# Currently the database has:

# # Shanks & Pottenger write that since 1970 most of Ontario has been like

# # Thunder Bay skipped DST in 1973.
# # Many smaller locales did not observe peacetime DST until 1974;
# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
#
# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
# right corner of page 1, it says that Toronto will return to standard
# time at 2 am Sunday morning (which agrees with the database), and that:
#
#     The one-hour setback will go into effect throughout most of Ontario,
#     except in areas like Windsor which remains on standard time all year.
#
# Windsor is, of course, a lot larger than Nipigon.
#
# I only came across this incidentally.  I don't know if Windsor began
# observing DST when Detroit did, or in 1974, or on some other date.
#
# By the way, the article continues by noting that:
#
#     Some cities in the United States have pushed the deadline back
#     three weeks and will change over from daylight saving in October.

# From Arthur David Olson (2010-07-17):
#
# "Standard Time and Time Zones in Canada" appeared in
# The Journal of The Royal Astronomical Society of Canada,
# volume 26, number 2 (February 1932) and, as of 2010-07-17,
# was available at
# <a href="http://adsabs.harvard.edu/full/1932JRASC..26...49S">
# http://adsabs.harvard.edu/full/1932JRASC..26...49S
# </a>
#
# It includes the text below (starting on page 57):
#
#   A list of the places in Canada using daylight saving time would
# require yearly revision. From information kindly furnished by
# the provincial governments and by the postmasters in many cities
# and towns, it is found that the following places used daylight sav-
# ing in 1930. The information for the province of Quebec is definite,
# for the other provinces only approximate:
#
# 	Province	Daylight saving time used
# Prince Edward Island	Not used.
# Nova Scotia		In Halifax only.
# New Brunswick		In St. John only.
# Quebec		In the following places:
# 			Montreal	Lachine
# 			Quebec		Mont-Royal
# 			Levis		Iberville
# 			St. Lambert	Cap de la Madeleine
# 			Verdun		Loretteville
# 			Westmount	Richmond
# 			Outremont	St. Jerome
# 			Longueuil	Greenfield Park
# 			Arvida		Waterloo
# 			Chambly-Canton	Beaulieu
# 			Melbourne	La Tuque
# 			St. Theophile	Buckingham
# Ontario		Used generally in the cities and towns along
# 			the southerly part of the province. Not
# 			used in the northwesterlhy part.
# Manitoba		Not used.
# Saskatchewan		In Regina only.
# Alberta		Not used.
# British Columbia	Not used.
#
#   With some exceptions, the use of daylight saving may be said to be limited
# to those cities and towns lying between Quebec city and Windsor, Ont.

# Time Zones was permanently moved about two hundred miles west to
# include the Thunder Bay area....  When Canada adopted daylight
# savings time in 1916, Fort William and Port Arthur, having done so
# already, did not change their clocks....  During the Second World
# War,... [t]he cities agreed to implement DST during the summer
# months for the remainder of the war years.

# Manitoba

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# Saskatchewan

# From Mark Brader (2003-07-26):
# The first actual adoption of DST in Canada was at the municipal
# level.  As the [Toronto] Star put it (1912-06-07), "While people
# elsewhere have long been talking of legislation to save daylight,
# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
# presumably late evening, as below), and would run until "the end of
# the summer".  The discrepancy between municipal time and railroad
# time was noted.

# From Paul Eggert (2003-07-27):
# Willett (1914-03) notes that DST "has been in operation ... in the
# City of Moose Jaw, Saskatchewan, for one year."

# From Paul Eggert (2006-03-22):
# Shanks & Pottenger say that since 1970 this region has mostly been as Regina.
# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
# Other western towns (e.g. Lloydminster) are like Edmonton.
# Matthews and Vincent (1998) write that Denare Beach and Creighton
# are like Winnipeg, in violation of Saskatchewan law.

# From W. Jones (1992-11-06):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other.  In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.

# From Chris Walton (2006-06-26):
# The Saskatchewan time act which was last updated in 1996 is about 30 pages
# long and rather painful to read.

# British Columbia

# From Paul Eggert (2006-03-22):
# Shanks & Pottenger write that since 1970 most of this region has
# been like Vancouver.
# Dawson Creek uses MST.  Much of east BC is like Edmonton.
# Matthews and Vincent (1998) write that Creston is like Dawson Creek.

# It seems though that (re: Creston) is not entirely correct:

# From Chris Walton (2011-12-01):
# There are two areas within the Canadian province of British Columbia
# that do not currently observe daylight saving:
# a) The Creston Valley (includes the town of Creston and surrounding area)
# b) The eastern half of the Peace River Regional District
# (includes the cities of Dawson Creek and Fort St. John)

# Earlier this year I stumbled across a detailed article about the time
# keeping history of Creston; it was written by Tammy Hardwick who is the
# manager of the Creston & District Museum. The article was written in May 2009.
# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260">
# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
# </a>
# According to the article, Creston has not changed its clocks since June 1918.
# i.e. Creston has been stuck on UTC-7 for 93 years.
# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.

# Unfortunately the exact date for the time change in June 1918 remains
# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
# as plausible as any other date (in June).  She also said that after writing the
# article she had discovered another time change in 1916; this is the subject
# of another article which she wrote in October 2010.
# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56">
# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
# </a>

# Here is a summary of the three clock change events in Creston's history:
# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
# Exact date unknown
# 2. Oct 1916: switch to Pacific Standard Time (GMT-8)
# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
# Exact date in June unknown; Sunday June 2 is a reasonable guess.
# note#1:
# On Oct 27/1918 when daylight saving ended in the rest of Canada,
# Creston did not change its clocks.
# note#2:
# During WWII when the Federal Government legislated a mandatory clock change,
# Creston did not oblige.
# note#3:
# There is no guarantee that Creston will remain on Mountain Standard Time
# (UTC-7) forever.
# The subject was debated at least once this year by the town Council.
# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html">
# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
# </a>

# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
# In Creston, that was handled by shifting the area to PST (-8:00) then applying
# summer time to cause the offset to be -7:00, the same as it had been before
# the change.  It can be argued that the timezone abbreviation during this
# period should be PDT rather than MST, but that doesn't seem important enough
# (to anyone) to further complicate the rules.

# The transition dates (and times) are guesses.

# Northwest Territories, Nunavut, Yukon

# From Paul Eggert (2006-03-22):
# Dawson switched to PST in 1973.  Inuvik switched to MST in 1979.
# Mathew Englander (1996-10-07) gives the following refs:
#	* 1967. Paragraph 28(34)(g) of the Interpretation Act, S.C. 1967-68,
#	c. 7 defines Yukon standard time as UTC-9.  This is still valid;
#	see Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1).
#	* C.O. 1973/214 switched Yukon to PST on 1973-10-28 00:00.
#	* O.I.C. 1980/02 established DST.
#	* O.I.C. 1987/056 changed DST to Apr firstSun 2:00 to Oct lastSun 2:00.
# Shanks & Pottenger say Yukon's 1973-10-28 switch was at 2:00; go

# to differentiate it from the Yellowknife region.

# From Paul Eggert (1999-09-20):
# <a href="http://www.nunavut.com/basicfacts/english/basicfacts_1territory.html">
# Basic Facts: The New Territory
# </a> (1999) reports that Pangnirtung operates on eastern time,
# and that Coral Harbour does not observe DST.  We don't know when
# Pangnirtung switched to eastern time; we'll guess 1995.

# From Rives McDow (1999-11-08):
# On October 31, when the rest of Nunavut went to Central time,
# Pangnirtung wobbled.  Here is the result of their wobble:
#
# The following businesses and organizations in Pangnirtung use Central Time:
#
#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
#	Eastern Arctic National Parks, A & D Specialist
#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator
#
# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not
# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,
# so it appears that the situation will last at least that long.
# The Nunavut Intergovernmental Affairs hopes that they will "come to

# The Nunavut government would allow its employees in Kugluktuk and
# Cambridge Bay to operate on central time year-round, putting them
# one hour behind the rest of Nunavut for six months during the winter.
# At the end of October the two communities had rebelled against
# Nunavut's unified time zone, refusing to shift to eastern time with
# the rest of the territory for the winter.  Cambridge Bay remained on
# central time, while Kugluktuk, even farther west, reverted to
# mountain time, which they had used before the advent of Nunavut's
# unified time zone in 1999.
#
# From Rives McDow (2001-01-20), quoting the Nunavut government:
# The preceding decision came into effect at midnight, Saturday Nov 4, 2000.

# From Paul Eggert (2000-12-04):
# Let's just keep track of the official times for now.

# From Rives McDow (2001-03-07):
# The premier of Nunavut has issued a ministerial statement advising
# that effective 2001-04-01, the territory of Nunavut will revert
# back to three time zones (mountain, central, and eastern).  Of the
# cities in Nunavut, Coral Harbor is the only one that I know of that
# has said it will not observe dst, staying on EST year round.  I'm
# checking for more info, and will get back to you if I come up with
# more.
# [Also see <http://www.nunatsiaq.com/nunavut/nvt10309_06.html> (2001-03-09).]

# From Gwillim Law (2005-05-21):
# According to maps at
# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SWE.jpg
# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SSE.jpg
# (both dated 2003), and
# http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp
# (from a 1998 Canadian Geographic article), the de facto and de jure time
# for Southampton Island (at the north end of Hudson Bay) is UTC-5 all year
# round.  Using Google, it's easy to find other websites that confirm this.
# I wasn't able to find how far back this time regimen goes, but since it
# predates the creation of Nunavut, it probably goes back many years....
# The Inuktitut name of Coral Harbour is Sallit, but it's rarely used.
#
# From Paul Eggert (2005-07-26):
# For lack of better information, assume that Southampton Island observed
# daylight saving only during wartime.

# From Chris Walton (2007-03-01):
# ... the community of Resolute (located on Cornwallis Island in
# Nunavut) moved from Central Time to Eastern Time last November.
# Basically the community did not change its clocks at the end of
# daylight saving....
# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html

# From Chris Walton (2011-03-21):
# Back in 2007 I initiated the creation of a new "zone file" for Resolute
# Bay. Resolute Bay is a small community located about 900km north of
# the Arctic Circle. The zone file was required because Resolute Bay had
# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
#
# According to new information which I received last week, Resolute Bay
# went back to using UTC-6 in the winter of 2007-2008...
#
# On March 11/2007 most of Canada went onto daylight saving. On March
# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
# talked to somebody that was both knowledgeable and helpful. I was able
# to confirm that Resolute Bay was still operating on UTC-5. It was
# explained to me that Resolute Bay had been on the Eastern Time zone
# (EST) in the winter, and was now back on the Central Time zone (CDT).
# i.e. the time zone had changed twice in the last year but the clocks
# had not moved. The residents had to know which time zone they were in
# so they could follow the correct TV schedule...
#
# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
# of the phone call, I decided to seek out an alternate source of
# information. I found an e-mail address for somebody by the name of
# Stephanie Adams whose job was listed as "Inns North Support Officer for
# Arctic Co-operatives." I was under the impression that Stephanie lived
# and worked in Resolute Bay...
#
# On March 14/2011 I phoned the hamlet office again. I was told that
# Resolute Bay had been using Central Standard Time over the winter of
# 2010-2011 and that the clocks had therefore been moved one hour ahead
# on March 13/2011. The person I talked to was aware that Resolute Bay
# had previously experimented with Eastern Standard Time but he could not
# tell me when the practice had stopped.
#
# On March 17/2011 I searched the Web to find an e-mail address of
# somebody that might be able to tell me exactly when Resolute Bay went
# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
# used to be the mayor of Resolute Bay and he apparently owns half the
# businesses including "South Camp Inn." This website has some info on
# Aziz:
# <a href="http://www.uphere.ca/node/493">
# http://www.uphere.ca/node/493
# </a>
#
# I sent Aziz an e-mail asking when Resolute Bay had stopped using
# Eastern Standard Time.
#
# Aziz responded quickly with this: "hi, The time was not changed for the
# 1 year only, the following year, the community went back to the old way
# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
# the winter Zulu plus 6 hrs"
#
# This of course conflicted with everything I had ascertained in November 2008.
#
# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
# may want to check with the weather office in Resolute Bay or do a
# search on the weather through Env. Canada. web site"
#
# If I had realized the Stephanie did not live in Resolute Bay I would
# never have contacted her.  I now believe that all the information I
# obtained in November 2008 should be ignored...
# I apologize for reporting incorrect information in 2008.

# Mexico

# From Paul Eggert (2001-03-05):
# The Investigation and Analysis Service of the
# Mexican Library of Congress (MLoC) has published a
# <a href="http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/">
# history of Mexican local time (in Spanish)
# </a>.
#
# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC.
# (In all cases we go with the MLoC.)
# S&P report that Baja was at -8:00 in 1922/1923.
# S&P say the 1930 transition in Baja was 1930-11-16.
# S&P report no DST during summer 1931.
# S&P report a transition at 1932-03-30 23:00, not 1932-04-01.

# From Gwillim Law (2001-02-20):
# There are some other discrepancies between the Decrees page and the
# tz database.  I think they can best be explained by supposing that
# the researchers who prepared the Decrees page failed to find some of
# the relevant documents.

# From Alan Perry (1996-02-15):
# A guy from our Mexico subsidiary finally found the Presidential Decree
# outlining the timezone changes in Mexico.
#
# ------------- Begin Forwarded Message -------------
#
# I finally got my hands on the Official Presidential Decree that sets up the
# rules for the DST changes. The rules are:
#
# 1. The country is divided in 3 timezones:
#    - Baja California Norte (the Mexico/BajaNorte TZ)
#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
#    - The rest of the country (the Mexico/General TZ)
#
# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
#    at 2:00 AM, the times in each zone are as follows:
#    BajaNorte: GMT+7
#    BajaSur:   GMT+6
#    General:   GMT+5
#
# 3. The rest of the year, the times are as follows:
#    BajaNorte: GMT+8
#    BajaSur:   GMT+7
#    General:   GMT+6
#
# The Decree was published in Mexico's Official Newspaper on January 4th.
#

# From Paul Eggert (1996-06-12):
# For an English translation of the decree, see
# <a href="http://mexico-travel.com/extra/timezone_eng.html">
# ``Diario Oficial: Time Zone Changeover'' (1996-01-04).
# </a>

# From Rives McDow (1998-10-08):
# The State of Quintana Roo has reverted back to central STD and DST times
# (i.e. UTC -0600 and -0500 as of 1998-08-02).

# From Rives McDow (2000-01-10):
# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
# zone 5 hours from the International Date Line, and will not observe daylight
# savings time so as to stay on the same time zone as the southern part of
# Arizona year round.

# From Jesper Norgaard, translating
# <http://www.reforma.com/nacional/articulo/064327/> (2001-01-17):
# In Oaxaca, the 55.000 teachers from the Section 22 of the National
# Syndicate of Education Workers, refuse to apply daylight saving each
# year, so that the more than 10,000 schools work at normal hour the
# whole year.

# From Gwillim Law (2001-01-19):
# <http://www.reforma.com/negocios_y_dinero/articulo/064481/> ... says
# (translated):...
# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced
# that Summer Time will be reduced from seven to five months, starting
# this year....
# <http://www.publico.com.mx/scripts/texto3.asp?action=pagina&pag=21&pos=p&secc=naci&date=01/17/2001>
# [translated], says "summer time will ... take effect on the first Sunday
# in May, and end on the last Sunday of September.

# From Arthur David Olson (2001-01-25):
# The 2001-01-24 traditional Washington Post contained the page one
# story "Timely Issue Divides Mexicans."...
# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
# Mexico City and its 20 million residents on a different time than
# the rest of the country..." In particular, Lopez Obrador would abolish
# observation of Daylight Saving Time.

# <a href="http://www.conae.gob.mx/ahorro/decretohorver2001.html#decre">
# Official statute published by the Energy Department
# </a> (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
# and Sonora with no DST.  This was reported by Jesper Norgaard (2001-02-03).

# From Paul Eggert (2001-03-03):
#
# <a href="http://www.latimes.com/news/nation/20010303/t000018766.html">
# James F. Smith writes in today's LA Times
# </a>
# * Sonora will continue to observe standard time.
# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
#   the Federal District will not adopt DST.
# * 4 of 16 district leaders announced they'll ignore the decree.
# * The decree does not affect federal-controlled facilities including
#   the airport, banks, hospitals, and schools.
#
# For now we'll assume that the Federal District will bow to federal rules.

# From Jesper Norgaard (2001-04-01):
# I found some references to the Mexican application of daylight
# saving, which modifies what I had already sent you, stating earlier
# that a number of northern Mexican states would go on daylight
# saving. The modification reverts this to only cover Baja California
# (Norte), while all other states (except Sonora, who has no daylight
# saving all year) will follow the original decree of president
# Vicente Fox, starting daylight saving May 6, 2001 and ending
# September 30, 2001.

# From Reuters (2001-09-04):
# Mexico's Supreme Court on Tuesday declared that daylight savings was
# unconstitutional in Mexico City, creating the possibility the
# capital will be in a different time zone from the rest of the nation
# next year....  The Supreme Court's ruling takes effect at 2:00
# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
# standard time. "This is so residents of the Federal District are not
# subject to unexpected time changes," a statement from the court said.

# From Jesper Norgaard Welen (2002-03-12):
# ... consulting my local grocery store(!) and my coworkers, they all insisted
# that a new decision had been made to reinstate US style DST in Mexico....
# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
# confirms this.  Sonora as usual is the only state where DST is not applied.

# From Paul Eggert (2006-03-22):
# Formerly there was an America/Ensenada zone, which differed from
# America/Tijuana only in that it did not observe DST from 1976
# through 1995.  This was as per Shanks (1999).  But Shanks & Pottenger say
# Ensenada did not observe DST from 1948 through 1975.  Guy Harris reports
# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
# DST-observance was a town-by-town matter back then.  This concerns
# data after 1970 so most likely there should be at least one Zone
# other than America/Tijuana for Baja, but it's not clear yet what its
# name or contents should be.

# From Arthur David Olson (1999-03-29):
# The 1999-03-28 exhibition baseball game held in Havana, Cuba, between
# the Cuban National Team and the Baltimore Orioles was carried live on
# the Orioles Radio Network, including affiliate WTOP in Washington, DC.
# During the game, play-by-play announcer Jim Hunter noted that
# "We'll be losing two hours of sleep...Cuba switched to Daylight Saving
# Time today."  (The "two hour" remark referred to losing one hour of
# sleep on 1999-03-28--when the announcers were in Cuba as it switched
# to DST--and one more hour on 1999-04-04--when the announcers will have
# returned to Baltimore, which switches on that date.)

# From Evert van der Veer via Steffen Thorsen (2004-10-28):
# Cuba is not going back to standard time this year.
# From Paul Eggert (2006-03-22):
# http://www.granma.cu/ingles/2004/septiembre/juev30/41medid-i.html
# says that it's due to a problem at the Antonio Guiteras
# thermoelectric plant, and says "This October there will be no return
# to normal hours (after daylight saving time)".
# For now, let's assume that it's a temporary measure.

# From Carlos A. Carnero Delgado (2005-11-12):
# This year (just like in 2004-2005) there's no change in time zone
# adjustment in Cuba.  We will stay in daylight saving time:
# http://www.granma.cu/espanol/2005/noviembre/mier9/horario.html

# From Jesper Norgaard Welen (2006-10-21):
# An article in GRANMA INTERNACIONAL claims that Cuba will end
# the 3 years of permanent DST next weekend, see
# http://www.granma.cu/ingles/2006/octubre/lun16/43horario.html
# "On Saturday night, October 28 going into Sunday, October 29, at 01:00,
# watches should be set back one hour -- going back to 00:00 hours -- returning
# to the normal schedule....

# From Paul Eggert (2007-03-02):
# http://www.granma.cubaweb.cu/english/news/art89.html, dated yesterday,
# says Cuban clocks will advance at midnight on March 10.
# For lack of better information, assume Cuba will use US rules,
# except that it switches at midnight standard time as usual.
#
# From Steffen Thorsen (2007-10-25):
# Carlos Alberto Fonseca Arauz informed me that Cuba will end DST one week
# earlier - on the last Sunday of October, just like in 2006.
#
# He supplied these references:

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm

#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.

# From Alexander Krivenyshev (2009-03-04)
# According to the Radio Reloj - Cuba will start Daylight Saving Time on
# midnight between Saturday, March 07, 2009 and Sunday, March 08, 2009-
# not on midnight March 14 / March 15 as previously thought.

# From Rives McDow (2000-12-01):
# Dominican Republic changed its mind and presidential decree on Tuesday,
# November 28, 2000, with a new decree.  On Sunday, December 3 at 1:00 AM the
# Dominican Republic will be reverting to 8 hours from the International Date
# Line, and will not be using DST in the foreseeable future.  The reason they
# decided to use DST was to be in synch with Puerto Rico, who was also going
# to implement DST.  When Puerto Rico didn't implement DST, the president
# decided to revert.

# Haiti
# From Gwillim Law (2005-04-15):
# Risto O. Nykanen wrote me that Haiti is now on DST.
# I searched for confirmation, and I found a
# <a href="http://www.haitianconsulate.org/time.doc"> press release
# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
# </a>.  Translated from French, it says:
#
#  "The Prime Minister's Communication Office notifies the public in general
#   and the press in particular that, following a decision of the Interior
#   Ministry and the Territorial Collectivities [I suppose that means the
#   provinces], Haiti will move to Eastern Daylight Time in the night from next
#   Saturday the 2nd to Sunday the 3rd.
#
#  "Consequently, the Prime Minister's Communication Office wishes to inform
#   the population that the country's clocks will be set forward one hour
#   starting at midnight.  This provision will hold until the last Saturday in
#   October 2005.
#
#  "Port-au-Prince, March 31, 2005"
#
# From Steffen Thorsen (2006-04-04):
# I have been informed by users that Haiti observes DST this year like
# last year, so the current "only" rule for 2005 might be changed to a
# "max" rule or to last until 2006. (Who knows if they will observe DST
# next year or if they will extend their DST like US/Canada next year).
#
# I have found this article about it (in French):
# http://www.haitipressnetwork.com/news.cfm?articleID=7612
#
# The reason seems to be an energy crisis.

# From Stephen Colebourne (2007-02-22):
# Some IATA info: Haiti won't be having DST in 2007.

# From Steffen Thorsen (2012-03-11):
# According to several news sources, Haiti will observe DST this year,
# apparently using the same start and end date as USA/Canada.
# So this means they have already changed their time.

# # Shanks & Pottenger write that since 1970 most of Ontario has been like

# # Thunder Bay skipped DST in 1973.
# # Many smaller locales did not observe peacetime DST until 1974;
# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
#
# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
# right corner of page 1, it says that Toronto will return to standard
# time at 2 am Sunday morning (which agrees with the database), and that:
#
#     The one-hour setback will go into effect throughout most of Ontario,
#     except in areas like Windsor which remains on standard time all year.
#
# Windsor is, of course, a lot larger than Nipigon.
#
# I only came across this incidentally.  I don't know if Windsor began
# observing DST when Detroit did, or in 1974, or on some other date.
#
# By the way, the article continues by noting that:

# On September 20 [1979]...DOT...officials decreed that on April 27,
# 1980, Juneau and other nearby communities would move to Yukon Time.
# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
# Pacific Time.
#
# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
# Department's September 1979 decision. Juneau and other communities in
# northern Southeast reverted to Pacific Time on October 26.
#
# On October 28 [1983]...the Metlakatla Indian Community Council voted

#
# According to DOT official Joanne Petrie, Indian reservations are not
# bound to follow time zones imposed by neighboring jurisdictions.
#
# (The last is consistent with how the database now handles the Navajo
# Nation.)

# From Arthur David Olson (2011-02-09):
# I just spoke by phone with a staff member at the Metlakatla Indian
# Community office (using contact information available at

# </a>).
# It's shortly after 1:00 here on the east coast of the United States;
# the staffer said it was shortly after 10:00 there. When I asked whether
# that meant they were on Pacific time, they said no--they were on their
# own time. I asked about daylight saving; they said it wasn't used. I
# did not inquire about practices in the past.

# From Chris Walton (2011-03-21):
# Back in 2007 I initiated the creation of a new "zone file" for Resolute
# Bay. Resolute Bay is a small community located about 900km north of
# the Arctic Circle. The zone file was required because Resolute Bay had
# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
#
# According to new information which I received last week, Resolute Bay
# went back to using UTC-6 in the winter of 2007-2008...
#
# On March 11/2007 most of Canada went onto daylight saving. On March
# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
# talked to somebody that was both knowledgeable and helpful. I was able
# to confirm that Resolute Bay was still operating on UTC-5. It was
# explained to me that Resolute Bay had been on the Eastern Time zone
# (EST) in the winter, and was now back on the Central Time zone (CDT).
# i.e. the time zone had changed twice in the last year but the clocks
# had not moved. The residents had to know which time zone they were in
# so they could follow the correct TV schedule...
#
# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
# of the phone call, I decided to seek out an alternate source of
# information. I found an e-mail address for somebody by the name of
# Stephanie Adams whose job was listed as "Inns North Support Officer for
# Arctic Co-operatives." I was under the impression that Stephanie lived
# and worked in Resolute Bay...
#
# On March 14/2011 I phoned the hamlet office again. I was told that
# Resolute Bay had been using Central Standard Time over the winter of
# 2010-2011 and that the clocks had therefore been moved one hour ahead
# on March 13/2011. The person I talked to was aware that Resolute Bay
# had previously experimented with Eastern Standard Time but he could not
# tell me when the practice had stopped.
#
# On March 17/2011 I searched the Web to find an e-mail address of
# somebody that might be able to tell me exactly when Resolute Bay went
# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
# used to be the mayor of Resolute Bay and he apparently owns half the
# businesses including "South Camp Inn." This website has some info on
# Aziz:
# <a href="http://www.uphere.ca/node/493">
# http://www.uphere.ca/node/493
# </a>
#
# I sent Aziz an e-mail asking when Resolute Bay had stopped using
# Eastern Standard Time.
#
# Aziz responded quickly with this: "hi, The time was not changed for the
# 1 year only, the following year, the community went back to the old way
# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
# the winter Zulu plus 6 hrs"
#
# This of course conflicted with everything I had ascertained in November 2008.
#
# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
# may want to check with the weather office in Resolute Bay or do a
# search on the weather through Env. Canada. web site"
#
# If I had realized the Stephanie did not live in Resolute Bay I would
# never have contacted her.  I now believe that all the information I
# obtained in November 2008 should be ignored...
# I apologize for reporting incorrect information in 2008.

# It seems though that (re: Creston) is not entirely correct:

# From Chris Walton (2011-12-01):
# There are two areas within the Canadian province of British Columbia
# that do not currently observe daylight saving:
# a) The Creston Valley (includes the town of Creston and surrounding area)
# b) The eastern half of the Peace River Regional District
# (includes the cities of Dawson Creek and Fort St. John)

# Earlier this year I stumbled across a detailed article about the time
# keeping history of Creston; it was written by Tammy Hardwick who is the
# manager of the Creston & District Museum. The article was written in May 2009.
# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260">
# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
# </a>
# According to the article, Creston has not changed its clocks since June 1918.
# i.e. Creston has been stuck on UTC-7 for 93 years.
# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.

# Unfortunately the exact date for the time change in June 1918 remains
# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
# as plausible as any other date (in June).  She also said that after writing the
# article she had discovered another time change in 1916; this is the subject
# of another article which she wrote in October 2010.
# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56">
# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
# </a>

# Here is a summary of the three clock change events in Creston's history:
# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
# Exact date unknown
# 2. Oct 1916: switch to Pacific Standard Time (GMT-8) 
# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
# Exact date in June unknown; Sunday June 2 is a reasonable guess.
# note#1:
# On Oct 27/1918 when daylight saving ended in the rest of Canada,
# Creston did not change its clocks.
# note#2:
# During WWII when the Federal Government legislated a mandatory clock change,
# Creston did not oblige.
# note#3:
# There is no guarantee that Creston will remain on Mountain Standard Time
# (UTC-7) forever.
# The subject was debated at least once this year by the town Council.
# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html">
# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
# </a>

# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
# In Creston, that was handled by shifting the area to PST (-8:00) then applying
# summer time to cause the offset to be -7:00, the same as it had been before
# the change.  It can be argued that the timezone abbreviation during this
# period should be PDT rather than MST, but that doesn't seem important enough
# (to anyone) to further complicate the rules.

# The transition dates (and times) are guesses.

# From Steffen Thorsen (2007-10-25):

# 
# He supplied these references:

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm

#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.

# # Shanks & Pottenger write that since 1970 most of Ontario has been like

# # Thunder Bay skipped DST in 1973.
# # Many smaller locales did not observe peacetime DST until 1974;

#
# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
# right corner of page 1, it says that Toronto will return to standard
# time at 2 am Sunday morning (which agrees with the database), and that:
#
#     The one-hour setback will go into effect throughout most of Ontario,
#     except in areas like Windsor which remains on standard time all year.
#
# Windsor is, of course, a lot larger than Nipigon.
#
# I only came across this incidentally.  I don't know if Windsor began
# observing DST when Detroit did, or in 1974, or on some other date.

# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
# Pacific Time.
#
# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the

#
# On October 28 [1983]...the Metlakatla Indian Community Council voted

#
# According to DOT official Joanne Petrie, Indian reservations are not

# </a>).
# It's shortly after 1:00 here on the east coast of the United States;
# the staffer said it was shortly after 10:00 there. When I asked whether
# that meant they were on Pacific time, they said no--they were on their

# From Chris Walton (2011-03-21):
# Back in 2007 I initiated the creation of a new "zone file" for Resolute
# Bay. Resolute Bay is a small community located about 900km north of
# the Arctic Circle. The zone file was required because Resolute Bay had
# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
#
# According to new information which I received last week, Resolute Bay
# went back to using UTC-6 in the winter of 2007-2008...
#
# On March 11/2007 most of Canada went onto daylight saving. On March
# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
# talked to somebody that was both knowledgeable and helpful. I was able
# to confirm that Resolute Bay was still operating on UTC-5. It was
# explained to me that Resolute Bay had been on the Eastern Time zone
# (EST) in the winter, and was now back on the Central Time zone (CDT).
# i.e. the time zone had changed twice in the last year but the clocks
# had not moved. The residents had to know which time zone they were in
# so they could follow the correct TV schedule...
#
# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
# of the phone call, I decided to seek out an alternate source of
# information. I found an e-mail address for somebody by the name of
# Stephanie Adams whose job was listed as "Inns North Support Officer for
# Arctic Co-operatives." I was under the impression that Stephanie lived
# and worked in Resolute Bay...
#
# On March 14/2011 I phoned the hamlet office again. I was told that
# Resolute Bay had been using Central Standard Time over the winter of
# 2010-2011 and that the clocks had therefore been moved one hour ahead
# on March 13/2011. The person I talked to was aware that Resolute Bay
# had previously experimented with Eastern Standard Time but he could not
# tell me when the practice had stopped.
#
# On March 17/2011 I searched the Web to find an e-mail address of
# somebody that might be able to tell me exactly when Resolute Bay went
# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
# used to be the mayor of Resolute Bay and he apparently owns half the
# businesses including "South Camp Inn." This website has some info on
# Aziz:
# <a href="http://www.uphere.ca/node/493">
# http://www.uphere.ca/node/493
# </a>
#
# I sent Aziz an e-mail asking when Resolute Bay had stopped using
# Eastern Standard Time.
#
# Aziz responded quickly with this: "hi, The time was not changed for the
# 1 year only, the following year, the community went back to the old way
# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
# the winter Zulu plus 6 hrs"
#
# This of course conflicted with everything I had ascertained in November 2008.
#
# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
# may want to check with the weather office in Resolute Bay or do a
# search on the weather through Env. Canada. web site"
#
# If I had realized the Stephanie did not live in Resolute Bay I would
# never have contacted her.  I now believe that all the information I
# obtained in November 2008 should be ignored...
# I apologize for reporting incorrect information in 2008.

  introduce permanent daylight saving time (similar to Russia) was
  reverted.

# The quote includes these two statements:
# 'Sunday the CPR went back to the old system of time...'
# '... The daylight saving scheme was dropped all over Canada at the same time,'
# These statements refer to a transition from daylight time to standard time
# that occurred nationally on Sunday October 27/1918.  This transition was
# also documented in the Saturday October 26/1918 edition of the Toronto Star.

# In light of that evidence, we alter the date from the earlier believed
# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day
# than Thursday) in all Canadian rulesets.

# It seems though that (re: Creston) is not entirely correct:

# From Chris Walton (2011-12-01):
# There are two areas within the Canadian province of British Columbia
# that do not currently observe daylight saving:
# a) The Creston Valley (includes the town of Creston and surrounding area)
# b) The eastern half of the Peace River Regional District
# (includes the cities of Dawson Creek and Fort St. John)

# Earlier this year I stumbled across a detailed article about the time
# keeping history of Creston; it was written by Tammy Hardwick who is the
# manager of the Creston & District Museum. The article was written in May 2009.
# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260">
# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
# </a>
# According to the article, Creston has not changed its clocks since June 1918.
# i.e. Creston has been stuck on UTC-7 for 93 years.
# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.

# Unfortunately the exact date for the time change in June 1918 remains
# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
# as plausible as any other date (in June).  She also said that after writing the
# article she had discovered another time change in 1916; this is the subject
# of another article which she wrote in October 2010.
# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56">
# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
# </a>

# Here is a summary of the three clock change events in Creston's history:
# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
# Exact date unknown
# 2. Oct 1916: switch to Pacific Standard Time (GMT-8) 
# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
# Exact date in June unknown; Sunday June 2 is a reasonable guess.
# note#1:
# On Oct 27/1918 when daylight saving ended in the rest of Canada,
# Creston did not change its clocks.
# note#2:
# During WWII when the Federal Government legislated a mandatory clock change,
# Creston did not oblige.
# note#3:
# There is no guarantee that Creston will remain on Mountain Standard Time
# (UTC-7) forever.
# The subject was debated at least once this year by the town Council.
# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html">
# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
# </a>

# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
# In Creston, that was handled by shifting the area to PST (-8:00) then applying
# summer time to cause the offset to be -7:00, the same as it had been before
# the change.  It can be argued that the timezone abbreviation during this
# period should be PDT rather than MST, but that doesn't seem important enough
# (to anyone) to further complicate the rules.

# The transition dates (and times) are guesses.

# From Steffen Thorsen (2005-04-12):
# I've got reports from 8 different people that Nicaragua just started
# DST on Sunday 2005-04-10, in order to save energy because of
# expensive petroleum.  The exact end date for DST is not yet
# announced, only "September" but some sites also say "mid-September".
# Some background information is available on the President's official site:
# http://www.presidencia.gob.ni/Presidencia/Files_index/Secretaria/Notas%20de%20Prensa/Presidente/2005/ABRIL/Gobierno-de-nicaragua-adelanta-hora-oficial-06abril.htm
# The Decree, no 23-2005 is available here:
# http://www.presidencia.gob.ni/buscador_gaceta/BD/DECRETOS/2005/Decreto%2023-2005%20Se%20adelanta%20en%20una%20hora%20en%20todo%20el%20territorio%20nacional%20apartir%20de%20las%2024horas%20del%2009%20de%20Abril.pdf
#
# From Paul Eggert (2005-05-01):
# The decree doesn't say anything about daylight saving, but for now let's
# assume that it is daylight saving and that they'll switch back on the
# 3rd Sunday in September.
#
# From Gwillim Law (2005-04-21):
# The Associated Press story on the time change, which can be found at
# http://www.lapalmainteractivo.com/guias/content/gen/ap/America_Latina/AMC_GEN_NICARAGUA_HORA.html
# and elsewhere, says (fifth paragraph, translated from Spanish):  "The last
# time that a change of clocks was applied to save energy was in the year 2000
# during the Arnoldo Aleman administration."...
# The northamerica file says that Nicaragua has been on UTC-6 continuously
# since December 1998.  I wasn't able to find any details of Nicaraguan time
# changes in 2000.  Perhaps a note could be added to the northamerica file, to
# the effect that we have indirect evidence that DST was observed in 2000.
#
# From Jesper Norgaard Welen (2005-11-02):
# Nicaragua left DST the 2005-10-02 at 00:00 (local time).

# We generate the files specified below to guard against old files with
# obsolete information being left in the time zone binary directory.
# We limit the list to names that have appeared in previous versions of
# this time zone package.
# We do these as separate Zones rather than as Links to avoid problems if
# a particular place changes whether it observes DST.
# We put these specifications here in the northamerica file both to
# increase the chances that they'll actually get compiled and to
# avoid the need to duplicate the US rules in another file.

# CBC News reported that Ontario and Manitoba have announced plans to
# follow the US change, and that Nova Scotia is considering it; see
# <http://www.cbc.ca/news/background/daylightsavingtime/> (2005-10-21).
# CBC news also reported that Prince Edward Island is the first
# province in Atlantic Canada to follow the US change, and that Quebec
# had agreed; see <http://www.cbc.ca/pei/story/pe_daylight_20051207.html>
# (2005-12-07).
#
# To reflect all this, the Canada and Winn rules have been adjusted to
# agree with the 2007 US change.  This means we assume most of Canada
# will fall into line.  However, Alberta, British Columbia,
# Newfoundland, Northwest Territories, and Yukon already have separate
# rules in our database, so for now we'll leave them alone, which
# means that we currently assume these regions will not change their
# rules and will disagree with the US starting in 2007.  This
# assumption is probably incorrect, with the possible exception of
# Newfoundland.  We plan to adjust the Edm, Vanc, StJohns, and NT_YK
# rules as the corresponding provinces make their announcements.

# Quebec

# From Paul Eggert (2006-07-09):
# Shanks & Pottenger write that since 1970 most of Quebec has been
# like Montreal.

# From Paul Eggert (2006-06-27):
# Matthews and Vincent (1998) also write that Quebec east of the -63
# meridian is supposed to observe AST, but residents as far east as
# Natashquan use EST/EDT, and residents east of Natashquan use AST.
# In "Official time in Quebec" the Quebec department of justice writes in
# http://www.justice.gouv.qc.ca/english/publications/generale/temps-regl-1-a.htm
# that "The residents of the Municipality of the
# Cote-Nord-du-Golfe-Saint-Laurent and the municipalities of Saint-Augustin,
# Bonne-Esperance and Blanc-Sablon apply the Official Time Act as it is
# written and use Atlantic standard time all year round. The same applies to
# the residents of the Native facilities along the lower North Shore."
# <http://www.assnat.qc.ca/eng/37legislature2/Projets-loi/Publics/06-a002.htm>
# says this common practice was codified into law as of 2007.
# For lack of better info, guess this practice began around 1970, contra to
# Shanks & Pottenger who have this region observing AST/ADT.

# From Paul Eggert (2006-07-09):
# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# From Paul Eggert (2006-01-20):
# It says "DOT is relocating the time zone boundary in Indiana to move Starke,
# Pulaski, Knox, Daviess, Martin, Pike, Dubois, and Perry Counties from the
# Eastern Time Zone to the Central Time Zone.... The effective date of
# this rule is 2:OO a.m. EST Sunday, April 2, 2006, which is the
# changeover date from standard time to Daylight Saving Time."
# Strictly speaking, this means the affected counties will change their
# clocks twice that night, but this obviously is in error.  The intent
# is that 01:59:59 EST be followed by 02:00:00 CDT.

# The act indicates that daylight savings ends at 2:00am.

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# From Paul Eggert (2006-06-27):
# Matthews and Vincent (1998) also write that Quebec east of the -63
# meridian is supposed to observe AST, but residents as far east as
# Natashquan use EST/EDT, and residents east of Natashquan use AST.
# In "Official time in Quebec" the Quebec department of justice writes in
# http://www.justice.gouv.qc.ca/english/publications/generale/temps-regl-1-a.htm
# that "The residents of the Municipality of the
# Cote-Nord-du-Golfe-Saint-Laurent and the municipalities of Saint-Augustin,

# says this common practice was codified into law as of 2007.

# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm

# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative

# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html

#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# # Shanks & Pottenger write that since 1970 most of Ontario has been like
# # Toronto.
# # Thunder Bay skipped DST in 1973.
# # Many smaller locales did not observe peacetime DST until 1974;
# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
#
# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
# right corner of page 1, it says that Toronto will return to standard
# time at 2 am Sunday morning (which agrees with the database), and that:
#
#     The one-hour setback will go into effect throughout most of Ontario,
#     except in areas like Windsor which remains on standard time all year.
#
# Windsor is, of course, a lot larger than Nipigon.
#
# I only came across this incidentally.  I don't know if Windsor began
# observing DST when Detroit did, or in 1974, or on some other date.
#
# By the way, the article continues by noting that:

#     three weeks and will change over from daylight saving in October.

# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the

# From Chris Walton (2011-03-21):
# Back in 2007 I initiated the creation of a new "zone file" for Resolute
# Bay. Resolute Bay is a small community located about 900km north of
# the Arctic Circle. The zone file was required because Resolute Bay had
# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
#
# According to new information which I received last week, Resolute Bay
# went back to using UTC-6 in the winter of 2007-2008...
#
# On March 11/2007 most of Canada went onto daylight saving. On March
# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
# talked to somebody that was both knowledgeable and helpful. I was able
# to confirm that Resolute Bay was still operating on UTC-5. It was
# explained to me that Resolute Bay had been on the Eastern Time zone
# (EST) in the winter, and was now back on the Central Time zone (CDT).
# i.e. the time zone had changed twice in the last year but the clocks
# had not moved. The residents had to know which time zone they were in
# so they could follow the correct TV schedule...
#
# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
# of the phone call, I decided to seek out an alternate source of
# information. I found an e-mail address for somebody by the name of
# Stephanie Adams whose job was listed as "Inns North Support Officer for
# Arctic Co-operatives." I was under the impression that Stephanie lived
# and worked in Resolute Bay...
#
# On March 14/2011 I phoned the hamlet office again. I was told that
# Resolute Bay had been using Central Standard Time over the winter of
# 2010-2011 and that the clocks had therefore been moved one hour ahead
# on March 13/2011. The person I talked to was aware that Resolute Bay
# had previously experimented with Eastern Standard Time but he could not
# tell me when the practice had stopped.
#
# On March 17/2011 I searched the Web to find an e-mail address of
# somebody that might be able to tell me exactly when Resolute Bay went
# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
# used to be the mayor of Resolute Bay and he apparently owns half the
# businesses including "South Camp Inn." This website has some info on
# Aziz:
# <a href="http://www.uphere.ca/node/493">
# http://www.uphere.ca/node/493
# </a>
#
# I sent Aziz an e-mail asking when Resolute Bay had stopped using
# Eastern Standard Time.
#
# Aziz responded quickly with this: "hi, The time was not changed for the
# 1 year only, the following year, the community went back to the old way
# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
# the winter Zulu plus 6 hrs"
#
# This of course conflicted with everything I had ascertained in November 2008.
#
# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
# may want to check with the weather office in Resolute Bay or do a
# search on the weather through Env. Canada. web site"
#
# If I had realized the Stephanie did not live in Resolute Bay I would
# never have contacted her.  I now believe that all the information I
# obtained in November 2008 should be ignored...
# I apologize for reporting incorrect information in 2008.

# she quotes the Friday November 1/1918 edition of the Creston Review.
# The quote includes these two statements:
# 'Sunday the CPR went back to the old system of time...'
# '... The daylight saving scheme was dropped all over Canada at the same time,'
# These statements refer to a transition from daylight time to standard time
# that occurred nationally on Sunday October 27/1918.  This transition was
# also documented in the Saturday October 26/1918 edition of the Toronto Star.

# In light of that evidence, we alter the date from the earlier believed
# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day
# than Thursday) in all Canadian rulesets.

# It seems though that (re: Creston) is not entirely correct:

# From Chris Walton (2011-12-01):
# There are two areas within the Canadian province of British Columbia
# that do not currently observe daylight saving:
# a) The Creston Valley (includes the town of Creston and surrounding area)
# b) The eastern half of the Peace River Regional District
# (includes the cities of Dawson Creek and Fort St. John)

# Earlier this year I stumbled across a detailed article about the time
# keeping history of Creston; it was written by Tammy Hardwick who is the
# manager of the Creston & District Museum. The article was written in May 2009.
# <a href="http://www.ilovecreston.com/?p=articles&t=spec&ar=260">
# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
# </a>
# According to the article, Creston has not changed its clocks since June 1918.
# i.e. Creston has been stuck on UTC-7 for 93 years.
# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.

# Unfortunately the exact date for the time change in June 1918 remains
# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
# as plausible as any other date (in June).  She also said that after writing the
# article she had discovered another time change in 1916; this is the subject
# of another article which she wrote in October 2010.
# <a href="http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56">
# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
# </a>

# Here is a summary of the three clock change events in Creston's history:
# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
# Exact date unknown
# 2. Oct 1916: switch to Pacific Standard Time (GMT-8) 
# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
# Exact date in June unknown; Sunday June 2 is a reasonable guess.
# note#1:
# On Oct 27/1918 when daylight saving ended in the rest of Canada,
# Creston did not change its clocks.
# note#2:
# During WWII when the Federal Government legislated a mandatory clock change,
# Creston did not oblige.
# note#3:
# There is no guarantee that Creston will remain on Mountain Standard Time
# (UTC-7) forever.
# The subject was debated at least once this year by the town Council.
# <a href="http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html">
# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
# </a>

# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
# In Creston, that was handled by shifting the area to PST (-8:00) then applying
# summer time to cause the offset to be -7:00, the same as it had been before
# the change.  It can be argued that the timezone abbreviation during this
# period should be PDT rather than MST, but that doesn't seem important enough
# (to anyone) to further complicate the rules.

# The transition dates (and times) are guesses.

# Saskatchewan, for one year."

# From David Bryan via Tory Tronrud, Director/Curator,
# Thunder Bay Museum (2003-11-12):
# There is some suggestion, however, that, by-law or not, daylight
# savings time was being practiced in Fort William and Port Arthur
# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to
# include the Thunder Bay area....  When Canada adopted daylight
# savings time in 1916, Fort William and Port Arthur, having done so

# From David Bryan via Tory Tronrud, Director/Curator,
# Thunder Bay Museum (2003-11-12):
# There is some suggestion, however, that, by-law or not, daylight
# savings time was being practiced in Fort William and Port Arthur
# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to
# include the Thunder Bay area....  When Canada adopted daylight
# savings time in 1916, Fort William and Port Arthur, having done so
# already, did not change their clocks....  During the Second World
# War,... [t]he cities agreed to implement DST during the summer
# months for the remainder of the war years.

# Some background information is available on the President's official site:

#
# From Paul Eggert (2005-05-01):

# and elsewhere, says (fifth paragraph, translated from Spanish):  "The last
# time that a change of clocks was applied to save energy was in the year 2000
# during the Arnoldo Aleman administration."...
# The northamerica file says that Nicaragua has been on UTC-6 continuously
# since December 1998.  I wasn't able to find any details of Nicaraguan time
# changes in 2000.  Perhaps a note could be added to the northamerica file, to

# CBC News reported that Ontario and Manitoba have announced plans to
# follow the US change, and that Nova Scotia is considering it; see
# <http://www.cbc.ca/news/background/daylightsavingtime/> (2005-10-21).
# CBC news also reported that Prince Edward Island is the first
# province in Atlantic Canada to follow the US change, and that Quebec
# had agreed; see <http://www.cbc.ca/pei/story/pe_daylight_20051207.html>
# (2005-12-07).
#
# To reflect all this, the Canada and Winn rules have been adjusted to
# agree with the 2007 US change.  This means we assume most of Canada
# will fall into line.  However, Alberta, British Columbia,
# Newfoundland, Northwest Territories, and Yukon already have separate
# rules in our database, so for now we'll leave them alone, which
# means that we currently assume these regions will not change their
# rules and will disagree with the US starting in 2007.  This
# assumption is probably incorrect, with the possible exception of
# Newfoundland.  We plan to adjust the Edm, Vanc, StJohns, and NT_YK
# rules as the corresponding provinces make their announcements.

# The act indicates that daylight savings ends at 2:00am.

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# From Steffen Thorsen (2007-10-25):
# Carlos Alberto Fonseca Arauz informed me that Cuba will end DST one week 
# earlier - on the last Sunday of October, just like in 2006.
# 
# He supplied these references:
# 
# http://www.prensalatina.com.mx/article.asp?ID=%7B4CC32C1B-A9F7-42FB-8A07-8631AFC923AF%7D&language=ES

# Here is also article from Granma (Cuba):
# 
# [Regira] el Horario Normal desde el [proximo] domingo 28 de octubre
# http://www.granma.cubaweb.cu/2007/10/24/nacional/artic07.html
# 
# http://www.worldtimezone.com/dst_news/dst_news_cuba03.html

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
# </a>
#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.

# Gwillim Law reports this source for daylight saving time in Mexico:
# <a href="http://www.spin.com.mx/verano/">
# Daylight saving time * SPIN-Internet (in Spanish)
# </a>
# Law (2000-03-09) translates it as follows:
#
# Standard time effective in Mexico takes its origin in the
# presidential decree of April 24, 1942.  The time of the 120th
# meridian applies to the state of Baja California; of the 105th
# meridian to the states of Baja California Sur, Sonora, Sinaloa, and
# Nayarit; and the time of the 90th meridian to the rest of the
# country.
#
# In the country, there have been several attempts made to adapt
# standard time with the object of arriving at a better use of
# daylight for social and economic activities.  In December, 1981 a
# permanent time zone was decreed for the states of Campeche, Yucatan,
# and Quintana Roo, displacing them from the 90th to the 75th
# meridian.  This disposition was annulled on December 2, 1982.
#
# In 1988 a Summer Time was established for the states of Tamaulipas,
# Nuevo Leon, Coahuila, and Durango, which meant that from the first
# Sunday in April to the last [Sunday] of October those states
# displaced their time from the 90th to the 75th meridian.  That
# disposition lasted for one year.

# His pamphlet ``A System of National Time for Railroads'' (1870)
# was the result of his proposals at the Convention of Railroad Trunk Lines
# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,

# From Rives McDow (1999-11-08):
# On October 31, when the rest of Nunavut went to Central time,
# Pangnirtung wobbled.  Here is the result of their wobble:
#
# The following businesses and organizations in Pangnirtung use Central Time:
#
#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
#	Eastern Arctic National Parks, A & D Specialist
#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator
#
# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not
# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,
# so it appears that the situation will last at least that long.
# The Nunavut Intergovernmental Affairs hopes that they will "come to
# their senses", but the locals evidently don't see any problem with
# the current state of affairs.

# From Arthur David Olson (2000-09-25):
# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
# In the introduction, Oboler spoke of "Eastern Peace Time."
# An AltaVista search turned up
# <a href="http://rowayton.org/rhs/hstaug45.html">:
# "When the time is announced over the radio now, it is 'Eastern Peace
# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
# </a> (August 1945) by way of confirmation.

# From Joseph Gallant <notquite@@hotmail.com>, citing
# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
# to switch to London for Atlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
# London which were to precede Mr. Atlee's speech.

# From Paul Eggert (2000-10-02):
# Shanks says that DST was called "War Time" in the US in 1919.
# In the light of the above, this seems suspect;

d1018 34
a1051 23
# Standard time effective in Mexico takes its origin in the
# presidential decree of April 24, 1942.  The time of the 120th
# meridian applies to the state of Baja California; of the 105th
# meridian to the states of Baja California Sur, Sonora, Sinaloa, and
# Nayarit; and the time of the 90th meridian to the rest of the
# country.
#
# In the country, there have been several attempts made to adapt
# standard time with the object of arriving at a better use of
# daylight for social and economic activities.  In December, 1981 a
# permanent time zone was decreed for the states of Campeche, Yucatan,
# and Quintana Roo, displacing them from the 90th to the 75th
# meridian.  This disposition was annulled on December 2, 1982.
#
# In 1988 a Summer Time was established for the states of Tamaulipas,
# Nuevo Leon, Coahuila, and Durango, which meant that from the first
# Sunday in April to the last [Sunday] of October those states
# displaced their time from the 90th to the 75th meridian.  That
# disposition lasted for one year.

# From Paul Eggert (2000-07-26):
# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981
# and 1988 DST experiments.  Go with spin.com.mx.

# At the end of October the two communities had rebelled against

# Shanks reports no DST during summer 1931.
# Shanks reports a transition at 1032-03-30 23:00, not 1932-04-01.
# Shanks does not report transitions for Baja in 1945 or 1948.

# James F. Smith writes in today's LA Times
# </a>
# * Sonora will continue to observe standard time.
# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
#   the Federal District will not adopt DST.
# * 4 of 16 district leaders announced they'll ignore the decree.
# * The decree does not affect federal-controlled facilities including

# For now we'll assume that the Federal District will bow to federal rules.

# I found some references to the Mexican application of daylight
# saving, which modifies what I had already sent you, stating earlier
# that a number of northern Mexican states would go on daylight
# saving. The modification reverts this to only cover Baja California
# (Norte), while all other states (except Sonora, who has no daylight

# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
# standard time. "This is so residents of the Federal District are not
# subject to unexpected time changes," a statement from the court said.

# From Paul Eggert (2001-03-05):
# Formerly there was an America/Ensenada zone, which differed from

# through 1995.  This was as per Shanks.  However, Guy Harris reports
# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which contradicts Shanks but does imply that
# DST-observance was a town-by-town matter back then.  This concerns

# other than America/Tijuana for Baja, but it's not clear yet what its

#
# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.

# On Aug. 14, stalling while talking steadily into the NBC networks' open

# From Mark Brader (2003-07-26):
# [According to the Toronto Star] Orillia, Ontario, adopted DST
# effective Saturday, 1912-06-22, 22:00; the article mentions that
# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
# have already done so.  In Orillia DST was to run until Saturday,
# 1912-08-31 (no time mentioned), but it was met with considerable
# hostility from certain segments of the public, and was revoked after
# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
# presumably that should be -07-06.  (1912-06-19, -07-12; also letters
# earlier in June).
#
# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).

# From Mark Brader (2003-07-26):
# The first actual adoption of DST in Canada was at the municipal
# level.  As the [Toronto] Star put it (1912-06-07), "While people
# elsewhere have long been talking of legislation to save daylight,
# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
# presumably late evening, as below), and would run until "the end of
# the summer".  The discrepancy between municipal time and railroad
# time was noted.

# From Paul Eggert (2003-07-27):

# From David Bryan via Tory Tronrud, Director/Curator,
# Thunder Bay Museum (2003-11-12):
# There is some suggestion, however, that, by-law or not, daylight
# savings time was being practiced in Fort William and Port Arthur
# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to
# include the Thunder Bay area....  When Canada adopted daylight
# savings time in 1916, Fort William and Port Arthur, having done so
# already, did not change their clocks....  During the Second World
# War,... [t]he cities agreed to implement DST during the summer
# months for the remainder of the war years.

# From Paul Eggert (2006-03-22):
# Since 1970, most of Indiana has been like America/Indiana/Indianapolis,
# with the following exceptions:
#
# - Gibson, Jasper, Lake, LaPorte, Newton, Porter, Posey, Spencer,
#   Vandenburgh, and Warrick counties have been like America/Chicago.
#
# - Dearborn and Ohio counties have been like America/New_York.
#
# - Clark, Floyd, and Harrison counties have been like
#   America/Kentucky/Louisville.
#
# - Daviess, Dubois, Knox, Martin, Perry, and Pulaski counties
#   have been like America/Indiana/Vincennes.

# - Crawford, Pike, Starke, and Switzerland counties have their own time zone
#   histories as noted below.
#
# Shanks partitioned Indiana into 345 regions, each with its own time history,
# and wrote ``Even newspaper reports present contradictory information.''
# Those Hoosiers!  Such a flighty and changeable people!
# Fortunately, most of the complexity occurred before our cutoff date of 1970.

# http://dmses.dot.gov/docimages/pdf95/382329_web.pdf [2.9 MB]
# From Paul Eggert (2006-01-20):
# It says "DOT is relocating the time zone boundary in Indiana to move Starke,
# Pulaski, Knox, Daviess, Martin, Pike, Dubois, and Perry Counties from the
# Eastern Time Zone to the Central Time Zone.... The effective date of
# this rule is 2:OO a.m. EST Sunday, April 2, 2006, which is the
# changeover date from standard time to Daylight Saving Time."
# Strictly speaking, this means the affected counties will change their
# clocks twice that night, but this obviously is in error.  The intent
# is that 01:59:59 EST be followed by 02:00:00 CDT.

# Quebec

# From Paul Eggert (2006-07-09):
# Shanks & Pottenger write that since 1970 most of Quebec has been
# like Montreal.

# From Paul Eggert (2006-06-27):
# Matthews and Vincent (1998) also write that Quebec east of the -63
# meridian is supposed to observe AST, but residents as far east as
# Natashquan use EST/EDT, and residents east of Natashquan use AST.
# In "Official time in Quebec" the Quebec department of justice writes in
# http://www.justice.gouv.qc.ca/english/publications/generale/temps-regl-1-a.htm
# that "The residents of the Municipality of the
# Cote-Nord-du-Golfe-Saint-Laurent and the municipalities of Saint-Augustin,
# Bonne-Esperance and Blanc-Sablon apply the Official Time Act as it is
# written and use Atlantic standard time all year round. The same applies to
# the residents of the Native facilities along the lower North Shore."
# <http://www.assnat.qc.ca/eng/37legislature2/Projets-loi/Publics/06-a002.htm>
# says this common practice was codified into law as of 2007.
# For lack of better info, guess this practice began around 1970, contra to

# From Paul Eggert (2006-07-09):
# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
# </a>.  Translated from French, it says:
#
#  "The Prime Minister's Communication Office notifies the public in general
#   and the press in particular that, following a decision of the Interior
#   Ministry and the Territorial Collectivities [I suppose that means the
#   provinces], Haiti will move to Eastern Daylight Time in the night from next

#
#  "Consequently, the Prime Minister's Communication Office wishes to inform

#
# From Steffen Thorsen (2006-04-04):
# I have been informed by users that Haiti observes DST this year like
# last year, so the current "only" rule for 2005 might be changed to a
# "max" rule or to last until 2006. (Who knows if they will observe DST
# next year or if they will extend their DST like US/Canada next year).
#
# I have found this article about it (in French):

# From Steffen Thorsen (2007-10-25):

# 
# He supplied these references:
#

# Here is also article from Granma (Cuba):
# 
# [Regira] el Horario Normal desde el [proximo] domingo 28 de octubre
# http://www.granma.cubaweb.cu/2007/10/24/nacional/artic07.html
# 
# http://www.worldtimezone.com/dst_news/dst_news_cuba03.html

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
# </a>
#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.

# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
# His pamphlet ``A System of National Time for Railroads'' (1870)
# was the result of his proposals at the Convention of Railroad Trunk Lines
# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
# and the most of the country soon followed suit.

# Pangnirtung switched to Eastern time; we'll guess 1995.
# We'll ignore the claim about Coral Harbour for now,
# since we have no further info.

# From Rives McDow (1999-11-08):
# On October 31, when the rest of Nunavut went to Central time,
# Pangnirtung wobbled.  Here is the result of their wobble:
#
# The following businesses and organizations in Pangnirtung use Central Time:
#
#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
#	Eastern Arctic National Parks, A & D Specialist
#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator
#
# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not
# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,
# so it appears that the situation will last at least that long.
# The Nunavut Intergovernmental Affairs hopes that they will "come to
# their senses", but the locals evidently don't see any problem with
# the current state of affairs.

# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
# central - or Nunavut time - for government offices, and eastern time
# for municipal offices and schools....  Igloolik [was similar but then]

@Update to the latest version from the vendor branch.  These files are
now identical with the distributed versions, which may cause some
abbreviations to change for people in obscure zones.  (The abbreviations
can be changed again if need be.)  It also changes the abbreviation
of Central European Time to `CET' from its previous value of `MET'
(a curious German-English hybrid).  Finally, we have finally rid
ourselves of those nasty ZONE-DESCR comments, which were a maintenance
nightmare, in favor of the new zone.tab file.  We are not using the
distribution's iso3166.tab file because we have our own list.

# Canada is reportedly lots easier than the US--leastways since 1951.
# I don't know what they did before then.
# 4.3BSD claims that it's perfectly regular.
# According to a posting in "comp.bugs.misc", "comp.unix.wizards", etc.
# on February 8, 1987, by Dave Sherman of the Law Society of Upper Canada,
# "...Canada (well, Ontario and at least some of the other provinces) are
# adopting the new daylight savings time rules...".  We assume all of
# Canada is doing so.

# From Bob Devine (January 28, 1988):
# All of Canada did have DST from your first rule except Saskatchewan.
# Which parts did not observe DST is hard to pinpoint but most of the
# province follows the rules.
# NOTE: those that didn't have DST for that rule, also
# probably did not have it for several years previous.

# From Arthur David Olson (January 21, 1989):
# April 3 fell on a Sunday in 1988; October 29 fell on a Sunday in 1989.  Ahem.
# Note claim that there's double DST in Newfoundland and that Yukon should
# be same as Pacific.

# From W. Jones (jones@@skdad.usask.ca) (November 6, 1992):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other.  In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.
#
# Here's how I would summarize things.  Establish a "Saskatchewan" CST
# time zone, and note that it officially exists as of 15 April 1966.  Any
# current exceptions can put themselves in the "Mountain" zone, since
# those are the rules they follow.  Any past exceptions can be forgotten,
# since that's what those who live here have done.

# From Arthur David Olson (November 21, 1992):
# East-Saskatchewan kept to avoid problems for folks using that zone by name;
# plain Saskatchewan added.

	Pacific/Belau -> Pacific/Palau
	America/Navajo -> America/Shiprock
and one new timezone has been added:

# From Paul Eggert (1995-12-19):

# but areas near Cincinnati and Louisville use those cities' timekeeping
# and in 1969 and 1970 the whole state observed daylight time;
# and there are other exceptions as noted below.
# Shanks partitions Indiana into 345 regions, each with its own time history,
# and writes ``Even newspaper reports present contradictory information.''
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Since 1970, EST-only Indiana has been like America/Indianapolis,
# with exceptions noted below for Crawford, Starke, and Switzerland counties.
# The parts of Indiana not listed below have been like America/Chicago,
# America/Louisville, or America/New_York.
#
# Other than Indianapolis, the Indiana place names are so nondescript
# that they would be ambiguous if we left them at the `America' level.
# So we reluctantly put them all in a subdirectory `America/Indiana'.
#
# Most of EST-only Indiana last observed DST in 1970.

# Michigan
#
# From Bob Devine (January 28, 1988):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1995-12-19):
# Shanks writes that Michigan started using standard time on 1885 Sep 18,
# but Howse (p 126) writes that Detroit kept
#
#	local time until 1900 when the City Council decreed that clocks should
#	be put back twenty-eight minutes to Central Standard Time.  Half the
#	city obeyed, half refused.  After considerable debate, the decision
#	was rescinded and the city reverted to Sun time.  A derisive offer to
#	erect a sundial in front of the city hall was referred to the
#	Committee on Sewers.  Then, in 1905, Central time was adopted
#	by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# A good source for time zone historical data in the US is
# Thomas G. Shanks, The American Atlas (5th edition),
# San Diego: ACS Publications, Inc. (1991).
# Make sure you have the errata sheet; the book is somewhat useless without it.

# From Paul Eggert (1996-06-12):
# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
# in his whimsical essay ``Turkey vs Eagle, McCauley is my Beagle'' (1784).
# Not everyone is happy with the results:
#
#	I don't really care how time is reckoned so long as there is some
#	agreement about it, but I object to being told that I am saving
#	daylight when my reason tells me that I am doing nothing of the kind.
#	I even object to the implication that I am wasting something
#	valuable if I stay in bed after the sun has risen.  As an admirer
#	of moonlight I resent the bossy insistence of those who want to
#	reduce my time for enjoying it.  At the back of the Daylight Saving
#	scheme I detect the bony, blue-fingered hand of Puritanism, eager
#	to push people into bed earlier, and get them up earlier, to make
#	them healthy, wealthy and wise in spite of themselves.

d162 21
a182 79
# From Paul Eggert (1995-12-19):
# Indiana generally observes either EST all year, or CST/CDT,
# but areas near Cincinnati and Louisville use those cities' timekeeping
# and in 1969 and 1970 the whole state observed daylight time;
# and there are other exceptions as noted below.
# Shanks partitions Indiana into 345 regions, each with its own time history,
# and writes ``Even newspaper reports present contradictory information.''
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Since 1970, EST-only Indiana has been like America/Indianapolis,
# with exceptions noted below for Crawford, Starke, and Switzerland counties.
# The parts of Indiana not listed below have been like America/Chicago,
# America/Louisville, or America/New_York.
#
# Other than Indianapolis, the Indiana place names are so nondescript
# that they would be ambiguous if we left them at the `America' level.

# Michigan
#
# From Bob Devine (1988-01-28):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1995-12-19):
# Shanks writes that Michigan started using standard time on 1885 Sep 18,
# but Howse (p 126) writes that Detroit kept
#
#	local time until 1900 when the City Council decreed that clocks should
#	be put back twenty-eight minutes to Central Standard Time.  Half the
#	city obeyed, half refused.  After considerable debate, the decision
#	was rescinded and the city reverted to Sun time.  A derisive offer to
#	erect a sundial in front of the city hall was referred to the
#	Committee on Sewers.  Then, in 1905, Central time was adopted
#	by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# From Paul Eggert (1997-10-17):
# msb@@sq.com writes that an article in the 1997-10-14 Toronto Star
# says that Atikokan, Ontario currently does not observe DST,

# He also writes that the
# <a href="http://www.gov.on.ca/MBS/english/publications/statregs/conttext.html">
# Ontario Time Act (1990, Chapter T.9)
# </a>
# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
# Officially Atikokan is therefore on CST/CDT, and most likely this report
# concerns a non-official time observed as a matter of local practice.
# For what it's worth, Shanks (1995) says that Atikokan has agreed with
# Rainy River ever since standard time was introduced.

# Saskatchewan

# From Paul Eggert (1996-06-12):
# Shanks writes that since 1970 most of this region has been like Regina.
# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
# Other western towns (e.g. Lloydminster) are like Edmonton.

# From W. Jones <jones@@skdad.usask.ca> (1992-11-06):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other.  In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.

# Professor Charles Ferdinand Dowd (1825-1904),
# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
# His pamphlet ``A System of National Time for Railroads'' (1870)
# was the result of his proposals at the Convention of Railroad Trunk Lines

# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
# and the most of the country soon followed suit.

# (Carnegie Library of Pittsburgh, 1927)</a>.
#
# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
# However, DST was imposed by the Standard Time Act of 1918, which
# was the first nationwide legal time standard, and apparently
# time was just called "Standard Time" or "Daylight Saving Time".

# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
# In the introduction, Oboler spoke of "Eastern Peace Time."
# An AltaVista search turned up
# <a href="http://rowayton.org/rhs/hstaug45.html">:
# "When the time is announced over the radio now, it is 'Eastern Peace
# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
# </a> (August 1945) by way of confirmation.

# From Joseph Gallant <notquite@@hotmail.com>, citing
# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
# to switch to London for Attlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
# London which were to precede Mr. Attlee's speech.

# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout.  From
# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
#
# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
# Any announcement from Asia would reach St. John's New York newsroom on a
# wire service teletype machine, which had prescribed signals for major news.
# Associated Press, for example, would ring five bells before spewing out
# typed copy of an important story, and 10 bells for news "of transcendental
# importance."
#
# On Aug. 14, stalling while talking steadily into the NBC networks' open
# microphone, St. John heard five bells and waited only to hear a sixth bell,
# before announcing confidently: "Ladies and gentlemen, World War II is over.
# The Japanese have agreed to our surrender terms."
#
# He had scored a 20-second scoop on other broadcasters.

# Daylight Saving Time web page (2002-01-23)</a> maintained by the
# Arizona State Library, Archives and Public Records.
# Between 1944-01-01 and 1944-04-01 the State of Arizona used standard
# time, but by federal law railroads, airlines, bus lines, military
# personnel, and some engaged in interstate commerce continued to
# observe war (i.e., daylight saving) time.  The 1944-03-17 Phoenix
# Gazette says that was the date the law changed, and that 04-01 was
# the date the state's clocks would change.  In 1945 the State of
# Arizona used standard time all year, again with exceptions only as
# mandated by federal law.  Arizona observed DST in 1967, but Arizona
# Laws 1968, ch. 183 (effective 1968-03-21) repealed DST.

# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to

#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator

# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not

#
# The Canadian Forces station at Alert uses Eastern Time while the

# Gjoa Haven, Taloyoak and Pelly Bay all use Mountain instead of
# Central Time and Southampton Island [in the Central zone] is not
# required to use daylight savings.

# At the end of October the two communities had rebelled against

# The premier of Nunavut has issued a ministerial statement advising

# There are some other discrepancies between the Decrees page and the

# the relevant documents.

# From Paul Eggert (2000-07-26):
# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981

# From Rives McDow (1998-10-08):
# The State of Quintana Roo has reverted back to central STD and DST times
# (i.e. UTC -0600 and -0500 as of 1998-08-02).

# From Rives McDow (2000-01-10):
# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
# zone 5 hours from the International Date Line, and will not observe daylight
# savings time so as to stay on the same time zone as the southern part of
# Arizona year round.

# From Jesper Norgaard, translating
# <http://www.reforma.com/nacional/articulo/064327/> (2001-01-17):
# In Oaxaca, the 55.000 teachers from the Section 22 of the National
# Syndicate of Education Workers, refuse to apply daylight saving each
# year, so that the more than 10,000 schools work at normal hour the
# whole year.

# <http://www.reforma.com/negocios_y_dinero/articulo/064481/> ... says
# (translated):...
# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced

# [translated], says "summer time will ... take effect on the first Sunday
# in May, and end on the last Sunday of September.

# From Arthur David Olson (2001-01-25):
# The 2001-01-24 traditional Washington Post contained the page one
# story "Timely Issue Divides Mexicans."...
# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
# Mexico City and its 20 million residents on a different time than
# the rest of the country..." In particular, Lopez Obrador would abolish
# observation of Daylight Saving Time.

# <a href="http://www.conae.gob.mx/ahorro/decretohorver2001.html#decre">
# Official statute published by the Energy Department
# </a> (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
# and Sonora with no DST.  This was reported by Jesper Norgaard (2001-02-03).

# From Paul Eggert (2001-03-03):
#
# <a href="http://www.latimes.com/news/nation/20010303/t000018766.html">
# James F. Smith writes in today's LA Times
# </a>
# * Sonora will continue to observe standard time.
# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
#   the Federal District will not adopt DST.
# * 4 of 16 district leaders announced they'll ignore the decree.
# * The decree does not affect federal-controlled facilities including
#   the airport, banks, hospitals, and schools.
#
# For now we'll assume that the Federal District will bow to federal rules.

# From Jesper Norgaard (2001-04-01):
# I found some references to the Mexican application of daylight
# saving, which modifies what I had already sent you, stating earlier
# that a number of northern Mexican states would go on daylight
# saving. The modification reverts this to only cover Baja California
# (Norte), while all other states (except Sonora, who has no daylight
# saving all year) will follow the original decree of president
# Vicente Fox, starting daylight saving May 6, 2001 and ending
# September 30, 2001.

# From Reuters (2001-09-04):
# Mexico's Supreme Court on Tuesday declared that daylight savings was
# unconstitutional in Mexico City, creating the possibility the
# capital will be in a different time zone from the rest of the nation
# next year....  The Supreme Court's ruling takes effect at 2:00
# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
# standard time. "This is so residents of the Federal District are not
# subject to unexpected time changes," a statement from the court said.

# From Jesper Norgaard Welen (2002-03-12):
# ... consulting my local grocery store(!) and my coworkers, they all insisted
# that a new decision had been made to reinstate US style DST in Mexico....
# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
# confirms this.  Sonora as usual is the only state where DST is not applied.

# From Paul Eggert (2001-03-05):
# Formerly there was an America/Ensenada zone, which differed from
# America/Tijuana only in that it did not observe DST from 1976
# through 1995.  This was as per Shanks.  However, Guy Harris reports
# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which contradicts Shanks but does imply that
# DST-observance was a town-by-town matter back then.  This concerns
# data after 1970 so most likely there should be at least one Zone
# other than America/Tijuana for Baja, but it's not clear yet what its
# name or contents should be.

# From Paul Eggert (1995-12-19):
# Indiana generally observes either EST all year, or CST/CDT,
# but areas near Cincinnati and Louisville use those cities' timekeeping
# and in 1969 and 1970 the whole state observed daylight time;
# and there are other exceptions as noted below.
# Shanks partitions Indiana into 345 regions, each with its own time history,
# and writes ``Even newspaper reports present contradictory information.''
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Since 1970, EST-only Indiana has been like America/Indianapolis,
# with exceptions noted below for Crawford, Starke, and Switzerland counties.
# The parts of Indiana not listed below have been like America/Chicago,
# America/Louisville, or America/New_York.
#
# Other than Indianapolis, the Indiana place names are so nondescript
# that they would be ambiguous if we left them at the `America' level.
# So we reluctantly put them all in a subdirectory `America/Indiana'.
#
# Most of EST-only Indiana last observed DST in 1970.

# Michigan
#
# From Bob Devine (January 28, 1988):
# Michigan didn't observe DST from 1968 to 1973.
#
# From Paul Eggert (1995-12-19):
# Shanks writes that Michigan started using standard time on 1885 Sep 18,
# but Howse (p 126) writes that Detroit kept
#
#	local time until 1900 when the City Council decreed that clocks should
#	be put back twenty-eight minutes to Central Standard Time.  Half the
#	city obeyed, half refused.  After considerable debate, the decision
#	was rescinded and the city reverted to Sun time.  A derisive offer to
#	erect a sundial in front of the city hall was referred to the
#	Committee on Sewers.  Then, in 1905, Central time was adopted
#	by city vote.
#
# This story is too entertaining to be false, so go with Howse over Shanks.
#
# Most of Michigan observed DST from 1973 on, but was a bit late in 1975.

# From Paul Eggert (1996-06-12):
# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
# in his whimsical essay ``Turkey vs Eagle, McCauley is my Beagle'' (1784).
# Not everyone is happy with the results:
#
#	I don't really care how time is reckoned so long as there is some
#	agreement about it, but I object to being told that I am saving
#	daylight when my reason tells me that I am doing nothing of the kind.
#	I even object to the implication that I am wasting something
#	valuable if I stay in bed after the sun has risen.  As an admirer
#	of moonlight I resent the bossy insistence of those who want to
#	reduce my time for enjoying it.  At the back of the Daylight Saving
#	scheme I detect the bony, blue-fingered hand of Puritanism, eager
#	to push people into bed earlier, and get them up earlier, to make
#	them healthy, wealthy and wise in spite of themselves.

# Saskatchewan

# From Paul Eggert (1996-06-12):
# Shanks writes that since 1970 most of this region has been like Regina.
# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
# Other western towns (e.g. Lloydminster) are like Edmonton.

# From W. Jones <jones@@skdad.usask.ca> (November 6, 1992):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other.  In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.

# A guy from our Mexico subsidiary finally found the Presidential Decree
# outlining the timezone changes in Mexico.
# 
# ------------- Begin Forwarded Message -------------
# 
# I finally got my hands on the Official Presidential Decree that sets up the
# rules for the DST changes. The rules are:
# 
# 1. The country is divided in 3 timezones:
#    - Baja California Norte (the Mexico/BajaNorte TZ)
#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
#    - The rest of the country (the Mexico/General TZ)
#    
# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
#    at 2:00 AM, the times in each zone are as follows:
#    BajaNorte: GMT+7
#    BajaSur:   GMT+6
#    General:   GMT+5
#    
# 3. The rest of the year, the times are as follows:
#    BajaNorte: GMT+8
#    BajaSur:   GMT+7
#    General:   GMT+6
#    
# The Decree was published in Mexico's Official Newspaper on January 4th.
# 
# -------------- End Forwarded Message --------------

# For an English translation of the decree,

# We'll ignore the claim about Coral Harbour for now,
# since we have no further info.

# From Rives McDow (1999-11-08):
# On October 31, when the rest of Nunavut went to Central time,
# Pangnirtung wobbled.  Here is the result of their wobble:
#
# The following businesses and organizations in Pangnirtung use Central Time:
#
#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
#	Eastern Arctic National Parks, A & D Specialist
#
# The following businesses and organizations in Pangnirtung use Eastern Time:
#
#	Hamlet office, All other businesses, Both schools, Airport operator
#
# This has made for an interesting situation there, which warranted the news.
# No one there that I spoke with seems concerned, or has plans to
# change the local methods of keeping time, as it evidently does not
# really interfere with any activities or make things difficult locally.
# They plan to celebrate New Year's turn-over twice, one hour apart,
# so it appears that the situation will last at least that long.
# The Nunavut Intergovernmental Affairs hopes that they will "come to
# their senses", but the locals evidently don't see any problem with
# the current state of affairs.

# From Michaela Rodrigue, writing in the
# <a href="http://www.nunatsiaq.com/archives/nunavut991130/nvt91119_17.html">
# Nunatsiaq News (1999-11-19)</a>:
# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
# central - or Nunavut time - for government offices, and eastern time
# for municipal offices and schools....  Igloolik [was similar but then]
# made the switch to central time on Saturday, Nov. 6.

# Gwillim Law reports this source for daylight saving time in Mexico:
# <a href="http://www.spin.com.mx/verano/">
# Daylight saving time * SPIN-Internet (in Spanish)
# </a>
# Law (2000-03-09) translates it as follows:
d1017 34
a1050 23
# Standard time effective in Mexico takes its origin in the
# presidential decree of April 24, 1942.  The time of the 120th
# meridian applies to the state of Baja California; of the 105th
# meridian to the states of Baja California Sur, Sonora, Sinaloa, and
# Nayarit; and the time of the 90th meridian to the rest of the
# country.
#
# In the country, there have been several attempts made to adapt
# standard time with the object of arriving at a better use of
# daylight for social and economic activities.  In December, 1981 a
# permanent time zone was decreed for the states of Campeche, Yucatan,
# and Quintana Roo, displacing them from the 90th to the 75th
# meridian.  This disposition was annulled on December 2, 1982.
#
# In 1988 a Summer Time was established for the states of Tamaulipas,
# Nuevo Leon, Coahuila, and Durango, which meant that from the first
# Sunday in April to the last [Sunday] of October those states
# displaced their time from the 90th to the 75th meridian.  That
# disposition lasted for one year.

# From Paul Eggert (2000-07-26):
# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981
# and 1988 DST experiments.  Go with spin.com.mx.

# From Arthur David Olson (2000-09-25):
# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
# In the introduction, Oboler spoke of "Eastern Peace Time."
# An AltaVista search turned up
# <a href="http://rowayton.org/rhs/hstaug45.html">:
# "When the time is announced over the radio now, it is 'Eastern Peace
# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
# </a> (August 1945) by way of confirmation.

# From Joseph Gallant <notquite@@hotmail.com>, citing
# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
# to switch to London for Atlee's address, but the American people
# never got to hear his speech live. According to one press account,
# CBS' Bob Trout was first to announce the word of Japan's surrender,
# but a few seconds later, NBC, ABC and Mutual also flashed the word
# of surrender, all of whom interrupting the bells of Big Ben in
# London which were to precede Mr. Atlee's speech.

# From Paul Eggert (2000-10-02):
# Shanks says that DST was called "War Time" in the US in 1919.
# In the light of the above, this seems suspect;

# that effective 2001-04-01, the territory of Nunavut will revert
# back to three time zones (mountain, central, and eastern).  Of the

# <a href="http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/">
# history of Mexican local time (in Spanish)

#
# Here are the discrepancies between Shanks and the MLoC.
# (In all cases we go with the MLoC.)
# Shanks reports that Baja was at -8:00 in 1922/1923.
# Shanks says the 1930 transition in Baja was 1930-11-16.
# Shanks reports no DST during summer 1931.
# Shanks reports a transition at 1032-03-30 23:00, not 1932-04-01.
# Shanks does not report transitions for Baja in 1945 or 1948.
# Shanks reports southern Mexico transitions on 1981-12-01, not 12-23.
# Shanks says Quintana Roo switched to -6:00 on 1982-12-02, and to -5:00
# on 1997-10-26 at 02:00.

# From Gwillim Law (2001-02-20):

# Official statute published by the Energy Department

# Formerly there was an America/Ensenada zone, which differed from

# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which contradicts Shanks but does imply that
# DST-observance was a town-by-town matter back then.  This concerns
# data after 1970 so most likely there should be at least one Zone
# other than America/Tijuana for Baja, but it's not clear yet what its

# Dominican Republic will be reverting to 8 hours from the International Date
# Line, and will not be using DST in the foreseeable future.  The reason they
# decided to use DST was to be in synch with Puerto Rico, who was also going

# decided to revert.

# From Mark Brader (2003-07-26):
# The first actual adoption of DST in Canada was at the municipal
# level.  As the [Toronto] Star put it (1912-06-07), "While people
# elsewhere have long been talking of legislation to save daylight,
# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
# presumably late evening, as below), and would run until "the end of
# the summer".  The discrepancy between municipal time and railroad
# time was noted.

# From Paul Eggert (2003-07-27):
# Willett (1914-03) notes that DST "has been in operation ... in the
# City of Moose Jaw, Saskatchewan, for one year."

# Thunder Bay Museum (2003-11-12):
# There is some suggestion, however, that, by-law or not, daylight
# savings time was being practiced in Fort William and Port Arthur
# before 1909.... [I]n 1910, the line between the Eastern and Central
# Time Zones was permanently moved about two hundred miles west to
# include the Thunder Bay area....  When Canada adopted daylight
# savings time in 1916, Fort William and Port Arthur, having done so
# already, did not change their clocks....  During the Second World
# War,... [t]he cities agreed to implement DST during the summer
# months for the remainder of the war years.

# I searched for confirmation, and I found a
# <a href="http://www.haitianconsulate.org/time.doc"> press release
# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
# </a>.  Translated from French, it says:
#
#  "The Prime Minister's Communication Office notifies the public in general
#   and the press in particular that, following a decision of the Interior
#   Ministry and the Territorial Collectivities [I suppose that means the
#   provinces], Haiti will move to Eastern Daylight Time in the night from next
#   Saturday the 2nd to Sunday the 3rd.
#
#  "Consequently, the Prime Minister's Communication Office wishes to inform
#   the population that the country's clocks will be set forward one hour
#   starting at midnight.  This provision will hold until the last Saturday in
#   October 2005.
#
#  "Port-au-Prince, March 31, 2005"

# From Steffen Thorsen (2005-04-12):
# I've got reports from 8 different people that Nicaragua just started
# DST on Sunday 2005-04-10, in order to save energy because of
# expensive petroleum.  The exact end date for DST is not yet
# announced, only "September" but some sites also say "mid-September".
# Some background information is available on the President's official site:
# http://www.presidencia.gob.ni/Presidencia/Files_index/Secretaria/Notas%20de%20Prensa/Presidente/2005/ABRIL/Gobierno-de-nicaragua-adelanta-hora-oficial-06abril.htm

#
# From Paul Eggert (2005-05-01):
# The decree doesn't say anything about daylight saving, but for now let's
# assume that it is daylight saving and that they'll switch back on the
# 3rd Sunday in September.
#
# From Gwillim Law (2005-04-21):
# The Associated Press story on the time change, which can be found at
# http://www.lapalmainteractivo.com/guias/content/gen/ap/America_Latina/AMC_GEN_NICARAGUA_HORA.html
# and elsewhere, says (fifth paragraph, translated from Spanish):  "The last
# time that a change of clocks was applied to save energy was in the year 2000
# during the Arnoldo Aleman administration."...
# The northamerica file says that Nicaragua has been on UTC-6 continuously
# since December 1998.  I wasn't able to find any details of Nicaraguan time
# changes in 2000.  Perhaps a note could be added to the northamerica file, to
# the effect that we have indirect evidence that DST was observed in 2000.

# New Brunswick's Time Definition Act
# <http://www.gnb.ca/0062/PDF-acts/t-06.pdf> says they change at 00:01, and
# <http://www.canlii.org/nb/laws/sta/t-6/20030127/whole.html> makes it
# clear that this has been the case since at least 1993.
# For now, assume it started in 1993.  The Office of the Premier announced
# <http://www.gnb.ca/cnb/news/pre/2005e1737pr.htm> (2005-12-23)
# that they will bring forward proposed amendments to harmonize with the US;
# for now assume that this will happen, but they'll still switch at 00:01.

# Here is a copy of the new official time act ...

# The act indicates that daylight savings ends at 2:00am.

# From Rob Douglas (2006-04-06):
# the old Manitoba Time Act - as amended by Bill 2, assented to
# March 27, 1987 ... said ...
# "between two o'clock Central Standard Time in the morning of
# the first Sunday of April of each year and two o'clock Central
# Standard Time in the morning of the last Sunday of October next
# following, one hour in advance of Central Standard Time."...
# I believe that the English legislation [of the old time act] had =
# been assented to (March 22, 1967)....
# Also, as far as I can tell, there was no order-in-council varying
# the time of Daylight Saving Time for 2005 and so the provisions of
# the 1987 version would apply - the changeover was at 2:00 Central
# Standard Time (i.e. not until 3:00 Central Daylight Time).

# From Paul Eggert (2006-04-10):
# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
# it was also 02:00s in 1966.

# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
# 2005-07-21 Chronicle-Journal, which said:
#
#	The clocks in Atikokan stay set on standard time year-round.
#	This means they spend about half the time on central time and
#	the other half on eastern time.
#
#	For the most part, the system works, Mayor Dennis Brown said.
#
#	"The majority of businesses in Atikokan deal more with Eastern
#	Canada, but there are some that deal with Western Canada," he
#	said.  "I don't see any changes happening here."
#
# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
# [New Osnaburgh] follow the same practice."

# From Garry McKinnon (2006-07-14) via Chris Walton:
# I chatted with a member of my board who has an outstanding memory
# and a long history in Atikokan (and in the telecom industry) and he
# can say for certain that Atikokan has been practicing the current
# time keeping since 1952, at least.

# From Paul Eggert (2006-07-17):
# Shanks & Pottenger say that Atikokan has agreed with Rainy River
# ever since standard time was introduced, but the information from
# McKinnon sounds more authoritative.  For now, assume that Atikokan
# switched to EST immediately after WWII era daylight saving time
# ended.  This matches the old (less-populous) America/Coral_Harbour
# entry since our cutoff date of 1970, so we can move
# America/Coral_Harbour to the 'backward' file.

# namely on 1971-10-24, but Mark Brader wrote (2003-05-31) that this
# is wrong, and that he had confirmed it by checking the 1971-10-30
# Toronto Star, which said that DST was ending 1971-10-31 as usual.

# From Arthur David Olson (2008-03-09):
# I'm in Maryland which is now observing United States Eastern Daylight
# Time. At 9:44 local time I used RealPlayer to listen to
# <a href="http://media.enet.cu/radioreloj">
# http://media.enet.cu/radioreloj
# </a>, a Cuban information station, and heard
# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
# indicating that Cuba is still on standard time.

# From Steffen Thorsen (2008-03-12):
# It seems that Cuba will start DST on Sunday, 2007-03-16...
# It was announced yesterday, according to this source (in Spanish):
# <a href="http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm">
# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm
# </a>
#
# Some more background information is posted here:
# <a href="http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html">
# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
# </a>
#
# The article also says that Cuba has been observing DST since 1963,
# while Shanks (and tzdata) has 1965 as the first date (except in the
# 1940's). Many other web pages in Cuba also claim that it has been
# observed since 1963, but with the exception of 1970 - an exception
# which is not present in tzdata/Shanks. So there is a chance we need to
# change some historic records as well.
#
# One example:
# <a href="http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm">
# http://www.radiohc.cu/espanol/noticias/mar07/11mar/hor.htm
# </a>

# From Jesper Norgaard Welen (2008-03-13):
# The Cuban time change has just been confirmed on the most authoritative
# web site, the Granma.  Please check out
# <a href="http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html">
# http://www.granma.cubaweb.cu/2008/03/13/nacional/artic10.html
# </a>
#
# Basically as expected after Steffen Thorsens information, the change
# will take place midnight between Saturday and Sunday.

# From Arthur David Olson (2008-03-12):
# Assume Sun>=15 (third Sunday) going forward.
