+# what is called "Beijing time." When Han make an appointment in Chinese
+# they implicitly use Beijing time.
+#
+# On the other hand, ethnic Uyghurs, who make up about half the
+# population of Xinjiang, typically use "Xinjiang time" which is two
+# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
+# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
+# local governments such as the Urumqi city government use both times in
+# publications, referring to what is popularly called Xinjiang time as
+# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
+# they almost invariably use Xinjiang time.
+#
+# (Their ethnic Han compatriots would typically have no clue of its
+# widespread use, however, because so extremely few of them are fluent in
+# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
+#
+# (...As with the rest of China there was a brief interval ending in 1990
+# or 1991 when summer time was in use.  The confusion was severe, with
+# the province not having dual times but four times in use at the same
+# time. Some areas remained on standard Xinjiang time or Beijing time and

+# We use POSIX-style signs in the Zone names and the output abbreviations,

+# POSIX has positive signs west of Greenwich, but many people expect
+# positive signs east of Greenwich.  For example, TZ='Etc/GMT+4' uses
+# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
+# (i.e. west of Greenwich) even though many people would expect it to
+# mean 4 hours ahead of UTC (i.e. east of Greenwich).
+#
+# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for

+#
+# One source is
+# < a href="http://government.ru/gov/results/16355/>
+# http://government.ru/gov/results/16355/
+# 
+# which, according to translate.google.com, begins "Decree of August 31,
+# 2011 No 725" and contains no other dates or "effective date" information.
+#
+# Another source is
+# 
+# http://www.rg.ru/2011/09/06/chas-zona-dok.html
+# 
+# which, according to translate.google.com, begins "Resolution of the
+# Government of the Russian Federation on August 31, 2011 N 725" and also
+# contains "Date first official publication: September 6, 2011 Posted on:
+# in the 'RG' - Federal Issue number 5573 September 6, 2011" but which
+# does not contain any "effective date" information.
+#
+# Another source is
+# 
+# http://en.wikipedia.org/wiki/Oymyakonsky_District#cite_note-RuTime-7
+# 
+# which, in note 8, contains "Resolution #725 of August 31, 2011...
+# Effective as of after 7 days following the day of the official publication"
+# but which does not contain any reference to September 6, 2011.
+#
+# The Wikipedia article refers to
+# 
+# http://base.consultant.ru/cons/cgi/online.cgi?req=doc;base=LAW;n=118896
+# 
+# which seems to copy the text of the government.ru page.
+#
+# Tobias Conradi combines Wikipedia's
+# "as of after 7 days following the day of the official publication"
+# with www.rg.ru's "Date of first official publication: September 6, 2011" to get
+# September 13, 2011 as the cutover date (unusually, a Tuesday, as Tobias Conradi notes).
+#
+# None of the sources indicates a time of day for changing clocks.

+#
+# 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:

 # 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.
+# 
+# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
+# 
+# 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.
+# 
+# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
+# 
+
+# 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.
+# 
+# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
+# 
+
+# 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 Chris Walton (2007-03-14):
-# Today I phoned the "hamlet office" to find out what Resolute was doing with
-# its clocks.
+# 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.
 #
-# 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)"...
+# 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:
+# 
+# http://www.uphere.ca/node/493
+# 
+#
+# 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.

 # during 2009, this timezone change will run from 00:00 the third Sunday
 # in March until 24:00 of the second Saturday in October.
 
-# From Arthur David Olson (2009-03-16):
-# The unofficial claim at
-# 
-# http://www.timeanddate.com/news/time/san-luis-new-time-zone.html
-# 
-# is that "The province will most likely follow the next daylight saving schedule,
-# which is planned for the second Sunday in October."
-
+# From Mariano Absatz (2009-10-16):
+# ...the Province of San Luis is a case in itself.
 #
+# The Law at
+# 
+# is ambiguous because establishes a calendar from the 2nd Sunday in
+# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
+# complement of that starting on the 2nd Sunday of March at 0:00 and
+# ending on the 2nd Saturday of March at 24:00.
+#
+# This clearly breaks every time the 1st of March or October is a Sunday.
+#
+# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
+# Sunday of October and March.
+#
+# The problem is that the changes in the rest of the Provinces that did
+# change in 2007/2008, were made according to the Federal Law and Decrees
+# that did so on the 3rd Sunday of October and March.
+#
+# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
+# (October 11th) at 0:00.
+#
+# So I guess a new set of rules, besides "Arg", must be made and the last
+# America/Argentina/San_Luis entries should change to use these...
+#
+# I'm enclosing a patch that does what I say... regretfully, the San Luis
+# timezone must be called "WART/WARST" even when most of the time (like,
+# right now) WARST == ART... that is, since last Sunday, all the country
+# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
+# of the country calls it "ART".
+# ...
+
+# From Alexander Krivenyshev (2010-04-09):
+# According to news reports from El Diario de la Republica Province San
+# Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time
+# after April 11, 2010--will continue to have same time as rest of
+# Argentina (UTC-3) (no DST).

+# TZ zone descriptions
+#
+# From Paul Eggert (1996-08-05):
+#
+# This file contains a table with the following columns:
+# 1.  ISO 3166 2-character country code.  See the file `iso3166.tab'.
+# 2.  Latitude and longitude of the zone's principal location
+#     in ISO 6709 sign-degrees-minutes-seconds format,
+#     either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
+#     first latitude (+ is north), then longitude (+ is east).
+# 3.  Zone name used in value of TZ environment variable.
+# 4.  Comments; present if and only if the country has multiple rows.
+#
+# Columns are separated by a single tab.
+# The table is sorted first by country, then an order within the country that
+# (1) makes some geographical sense, and
+# (2) puts the most populous zones first, where that does not contradict (1).
+#
+# Lines beginning with `#' are comments.
