-# From Ephraim Silverberg (2002-07-07):
-#
-# The Israeli government today adopted a proposal by Minister of Interior
-# Eli Yishai to shorten the period of Daylight Savings Time for the year
-# 2002 (only -- the dates for 2003 and 2004 are, so far, unaffected).
-#
-# The proposed date to Daylight Savings Time is September 13, 2002 instead
-# of the current date: October 7, 2002.  The hour of changeover has not
-# yet been decided.
-#
-# (2002-07-10):
-# While today the Knesset passed the initial proposal to reduce DST by
-# some three weeks, a new compromise is being worked out between
-# Minister of Justice Meir Sheetrit and Minister of Interior Eli
-# Yishai to revert to standard time for a period of 48-96 _hours_
-# (sic) around the Yom Kippur fast day (September 15-16) and then go
-# *back* to DST until the end of October.  The details of the proposal
-# have yet to be worked out, but the second and final readings of the
-# bill have until July 24 to pass.
-#
-# (2002-07-25):
-# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article
-# to my attention:
-#
-#	http://www.ynet.co.il/articles/0,7340,L-2019315,00.html
-#
-# Hence, the proposal to shorten DST was withdrawn yesterday and the timezone
-# files that have been in effect since July 2000 are still valid for all of
-# 2002.
-#
-# Please note that the article mentions that the Shas MK's intend to
-# bring up their amendment for future years (2003 and beyond).  What this
-# means exactly is anyone's guess since there are no set dates yet beyond
-# 2004 and the end day set for 2003 and 2004 is already the 7th of Tishrei
-# (i.e. before the fast of Yom Kippur).  The only thing they may want to
-# change is the start date of DST in 2003 from Mar.28.03 (24th of Adar II)
-# to Apr.18.03 (16th of Nisan) so that the Passover Seder will take place
-# during Standard Time.  The start date for 2004 is already Nisan 16th.

+# ... what happened was that the former Kazakhstan Eastern time zone

+# closer to UTC is the former Western zone (probably still called the
+# same), encompassing four provinces in the west: Aqtobe, Atyrau,

+# <http://today.reuters.co.uk/news/newsArticle.aspx?type=scienceNews&storyID=2006-04-12T172228Z_01_COL295762_RTRIDST_0_SCIENCE-SRILANKA-TIME-DC.XML>
+# [The Tamil Tigers] never accepted the original 1996 time change and simply
+# kept their clocks set five and a half hours ahead of Greenwich Mean
+# Time (GMT), in line with neighbor India.
+# From Paul Eggert (2006-04-18):
+# People who live in regions under Tamil control can use TZ='Asia/Calcutta',
+# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
+
+# From K Sethu (2006-04-25):
+# I think the abbreviation LKT originated from the world of computers at
+# the time of or subsequent to the time zone changes by SL Government
+# twice in 1996 and probably SL Government or its standardization
+# agencies never declared an abbreviation as a national standard.
+#
+# I recollect before the recent change the government annoucemments
+# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
+# Time and no mention was made about the abbreviation.
+#
+# If we look at Sri Lanka Department of Government's "Official News
+# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
+# use SLT as abbreviation in time stamp at the beginning of each news
+# item....
+#
+# Within Sri Lanka I think LKT is well known among computer users and
+# adminsitrators.  In my opinion SLT may not be a good choice because the
+# nation's largest telcom / internet operator Sri Lanka Telcom is well
+# known by that abbreviation - simply as SLT (there IP domains are
+# slt.lk and sltnet.lk).
+#
+# But if indeed our government has adopted SLT as standard abbreviation
+# (that we have not known so far) then  it is better that it be used for
+# all computers.
+
+# From Paul Eggert (2006-04-25):
+# One possibility is that we wait for a bit for the dust to settle down
+# and then see what people actually say in practice.

 # From Rives McDow (2002-04-09):
 # The most interesting region I have found consists of three towns on the
-# southern coast of Australia, population 10 at last report, along with
-# 50,000 sheep, about 100 kilometers long and 40 kilometers into the
-# continent.  The primary town is Madura, with the other towns being
-# Mundrabilla and Eucla.  According to the sheriff of Madura, the
-# residents got tired of having to change the time so often, as they are
-# located in a strip overlapping the border of South Australia and Western
-# Australia.  South Australia observes daylight saving time; Western
+# southern coast....  South Australia observes daylight saving time; Western
 # Australia does not.  The two states are one and a half hours apart.  The
 # residents decided to forget about this nonsense of changing the clock so
 # much and set the local time 20 hours and 45 minutes from the
 # international date line, or right in the middle of the time of South
-# Australia and Western Australia.  As it only affects about 10 people and
-# tourists staying at the Madura Motel, it has never really made as big an
-# impact as Broken Hill.  However, as tourist visiting there or anyone
-# calling the local sheriff will attest, they do keep time in this way.
+# Australia and Western Australia....
 #
 # From Paul Eggert (2002-04-09):
 # This is confirmed by the section entitled
 # "What's the deal with time zones???" in
-# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>,
-# which says a few other things:
+# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>.
+#
+# From Alex Livingston (2006-12-07):
+# ... it was just on four years ago that I drove along the Eyre Highway,
+# which passes through eastern Western Australia close to the southern
+# coast of the continent.
 #
-# * Border Village, SA also is 45 minutes ahead of Perth.
-# * The locals call this time zone "central W.A. Time" (presumably "CWAT").
-# * The locals also call Western Australia time "Perth time".
+# I paid particular attention to the time kept there. There can be no
+# dispute that UTC+08:45 was considered "the time" from the border
+# village just inside the border with South Australia to as far west
+# as just east of Caiguna. There can also be no dispute that Eucla is
+# the largest population centre in this zone....
 #
-# It's not clear from context whether everyone in Western Australia
-# knows of this naming convention, or whether it's just the people in
-# this subregion.
+# Now that Western Australia is observing daylight saving, the
+# question arose whether this part of the state would follow suit. I
+# just called the border village and confirmed that indeed they have,
+# meaning that they are now observing UTC+09:45.
+# 
+# (2006-12-09):
+# I personally doubt that either experimentation with daylight saving
+# in WA or its introduction in SA had anything to do with the genesis
+# of this time zone.  My hunch is that it's been around since well
+# before 1975.  I remember seeing it noted on road maps decades ago.
+
+# From Paul Eggert (2006-12-15):
+# For lack of better info, assume the tradition dates back to the
+# introduction of standard time in 1895.

 # mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
 # has a rather arbitrary nature.  The straight-line boundaries between Pacific
 # island nations that are shown on many maps are based on an international
-# convention, but are not legally binding national borders.
-#
-# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
-# legal time on the high seas would be zone time, i.e., the standard time at
-# the nearest meridian that is a multiple of fifteen degrees.  The date is
+# convention, but are not legally binding national borders.... The date is
 # governed by the IDL; therefore, even on the high seas, there may be some
 # places as late as fourteen hours later than UTC.  And, since the IDL is not
 # an international standard, there are some places on the high seas where the
 # correct date is ambiguous.
+
+# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
+# Before 1920, all ships kept local apparent time on the high seas by setting
+# their clocks at night or at the morning sight so that, given the ship's
+# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
+# meridian (12 o'clock = local apparent noon).  During 1917, at the
+# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
+# ships, both military and civilian, should adopt hourly standard time zones
+# on the high seas.  Whenever a ship was within the territorial waters of any
+# nation it would use that nation's standard time.  The captain was permitted
+# to change his ship's clocks at a time of his choice following his ship's
+# entry into another zone time--he often chose midnight.  These zones were
+# adopted by all major fleets between 1920 and 1925 but not by many
+# independent merchant ships until World War II.

+# [introducing standard time] was in effect from 1894-01-01....
+# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
+# confirms this, and states that the law was put forth 1893-03-29.
+#
+# The EU treaty with effect from 1973:
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
+#
+# This provoked a new law from 1974 to make possible summer time changes
+# in subsequenet decrees with the law
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
+#
+# It seems however that no decree was set forward until 1980.  I have
+# not found any decree, but in another related law, the effecting DST
+# changes are stated explicitly to be from 1980-04-06 at 02:00 to
+# 1980-09-28 at 02:00.  If this is true, this differs slightly from
+# the EU rule in that DST runs to 02:00, not 03:00.  We don't know
+# when Denmark began using the EU rule correctly, but we have only
+# confirmation of the 1980-time, so I presume it was correct in 1981:
+# The law is about the management of the extra hour, concerning
+# working hours reported and effect on obligatory-rest rules (which

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

-# and in 1969 and 1970 the whole state observed daylight time;

+# 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.

+# Shanks partitioned Indiana into 345 regions, each with its own time history,

+# 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

 # So we reluctantly put them all in a subdirectory `America/Indiana'.
-#
-# Most of EST-only Indiana last observed DST in 1970.
 
-# From Paul Eggert (2001-03-06), following a tip by Markus Kuhn:
-# Pam Belluck reported in the New York Times (2001-01-31) that the
-# Indiana Legislature is considering a bill to adopt DST statewide.
-# Her article mentioned Vevay, whose post office observes a different
-# time zone from Danner's Hardware across the street.
+# From Paul Eggert (2005-08-16):

+# 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

 # 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.

+# 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

 # 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.

+# http://www.lanacion.com.ar/04/05/28/de_605203.asp

+# The following eight (8) provinces pulled clocks back to UTC-04:00 at
+# midnight Monday May 31st. (that is, the night between 05/31 and 06/01).
+# Apparently, all nine provinces would go back to UTC-03:00 at the same
+# time in October 17th.
+#
+# Catamarca, Chubut, La Rioja, San Juan, San Luis, Santa Cruz,
+# Tierra del Fuego, Tucuman.
+#
+# From Mariano Absatz (2004-06-14):
+# ... this weekend, the Province of Tucuman decided it'd go back to UTC-03:00
+# yesterday midnight (that is, at 24:00 Saturday 12th), since the people's
+# annoyance with the change is much higher than the power savings obtained....
+#
+# From Gwillim Law (2004-06-14):
+# http://www.lanacion.com.ar/04/06/10/de_609078.asp ...
+#     "The time change in Tierra del Fuego was a conflicted decision from
+#   the start.  The government had decreed that the measure would take
+#   effect on June 1, but a normative error forced the new time to begin
+#   three days earlier, from a Saturday to a Sunday....
+# Our understanding was that the change was originally scheduled to take place
+# on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other
+# provinces).  Sunday was May 30, only two days earlier.  So the article
+# contains a contradiction.  I would give more credence to the Saturday/Sunday
+# date than the "three days earlier" phrase, and conclude that Tierra del
+# Fuego set its clocks back at 2004-05-30 00:00.
+#
+# From Steffen Thorsen (2004-10-05):
+# The previous law 7210 which changed the province of Mendoza's time zone
+# back in May have been modified slightly in a new law 7277, which set the
+# new end date to 2004-09-26 (original date was 2004-10-17).

 # Because of the same drought, the government decided to end DST later,
 # on April 3, (one-time change).
 
-# From Gwillim Law (2001-05-04):
-# I came across another article in "La Tercera" about Chilean DST.
-# <http://www.tercera.cl/diario/2000/10/13/t-extras.html>
-# It clearly confirms my earlier suggestion, that DST begins at 22:00
-# on Easter Island....  But it also seems to be saying that the
-# observance of DST in Chile began in 1966, rather than 1969 as
-# ... [Shanks] has it....
-#
-# My translation:
-#
-# "The Chilean Army has announced that summer time will begin tomorrow,
-# Saturday, October 14 in continental Chile, insular Chile, and
-# Antarctica, as provided by Supreme Decree 25 of January 11, 1966.
-# By the preceding, official time in continental Chile and Chilean
-# Antarctic, and official time in Western Insular Chile, which applies
-# to Easter Island and Sala y Gomez Island, will be set forward at
-# midnight and at 22:00, respectively, by 20 minutes."
+# From Oscar van Vlijmen (2006-10-08):
+# http://www.horaoficial.cl/cambio.htm
 
-# From Paul Eggert (2001-05-04):
-# Go with this article in preference to Shanks's 1969 date for modern DST.
-# Assume this rule has been used since DST was introduced in the islands.
+# From Jesper Norgaard Welen (2006-10-08):
+# I think that there are some obvious mistakes in the suggested link
+# from Oscar van Vlijmen,... for instance entry 66 says that GMT-4
+# ended 1990-09-12 while entry 67 only begins GMT-3 at 1990-09-15
+# (they should have been 1990-09-15 and 1990-09-16 respectively), but
+# anyhow it clears up some doubts too.
 
-# From Paul Eggert (2002-10-24):
-# <http://www.shoa.cl/shoa/faqhoraoficial.htm> gives many details that
-# disagree with the following table, but we haven't had time to compare them.
+# From Paul Eggert (2006-12-27):
+# The following data for Chile and America/Santiago are from
+# <http://www.horaoficial.cl/horaof.htm> (2006-09-20), transcribed by
+# Jesper Norgaard Welen.  The data for Pacific/Easter are from Shanks
+# & Pottenger, except with DST transitions after 1932 cloned from
+# America/Santiago.  The pre-1980 Pacific/Easter data are dubious,
