Shanks and Rique Pottenger, The International Atlas (6th edition), +# San Diego: ACS Publications, Inc. (2003). +# +# Gwillim Law writes that a good source +# for recent time zone data is the International Air Transport +# Association's Standard Schedules Information Manual (IATA SSIM), +# published semiannually. Law sent in several helpful summaries +# of the IATA's data after 1990. +# +# Except where otherwise noted, Shanks & Pottenger is the source for +# entries through 1990, and IATA SSIM is the source for entries afterwards. +# +# Another source occasionally used is Edward W. Whitman, World Time Differences, +# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which +# I found in the UCLA library. +# +# A reliable and entertaining source about time zones is +# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). +# +# Previous editions of this database used WAT, CAT, SAT, and EAT +# for +0:00 through +3:00, respectively, +# but Mark R V Murray reports that +# `SAST' is the official abbreviation for +2:00 in the country of South Africa, +# `CAT' is commonly used for +2:00 in countries north of South Africa, and +# `WAT' is probably the best name for +1:00, as the common phrase for +# the area that includes Nigeria is ``West Africa''. +# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference. +# +# To make things confusing, `WAT' seems to have been used for -1:00 long ago; +# I'd guess that this was because people needed _some_ name for -1:00, +# and at the time, far west Africa was the only major land area in -1:00. +# This usage is now obsolete, as the last use of -1:00 on the African +# mainland seems to have been 1976 in Western Sahara. +# +# To summarize, the following abbreviations seem to have some currency: +# -1:00 WAT West Africa Time (no longer used) +# 0:00 GMT Greenwich Mean Time +# 2:00 CAT Central Africa Time +# 2:00 SAST South Africa Standard Time +# and Murray suggests the following abbreviation: +# 1:00 WAT West Africa Time +# I realize that this leads to `WAT' being used for both -1:00 and 1:00 +# for times before 1976, but this is the best I can think of +# until we get more information. +# +# I invented the following abbreviations;

We have other instances of ambiguity +# (e.g. "IST" denoting both "Israel Standard Time" and "Indian +# Standard Time"), and they are not likely to go away any time soon. +# In the old days, some software mistakenly relied on unique +# abbreviations, but this is becoming less true with time, and I don't +# think it's that important to cater to such software these days. +# +# On the other hand, there is another motivation for unambiguous +# abbreviations: it cuts down on human confusion. This is +# particularly true for Australia, where "EST" can mean one thing for +# time T and a different thing for time T plus 1 second. +# +# * Does the relevant legislation indicate which abbreviations should be used? +# +# Here I tend to think that things are a mess, just as they are in +# many other countries. We Americans are currently disagreeing about +# which abbreviation to use for the newly legislated Chamorro Standard +# Time, for example. +# +# Personally, I would prefer to use common practice; I would like to +# refer to legislation only for examples of common practice, or as a +# tiebreaker. +# +# * Do Australians more often use "Eastern Daylight Time" or "Eastern +# Summer Time"? Do they typically prefix the time zone names with +# the word "Australian"? +# +# My own impression is that both "Daylight Time" and "Summer Time" are +# common and are widely understood, but that "Summer Time" is more +# popular; and that the leading "A" is also common but is omitted more +# often than not. I just used AltaVista advanced search and got the +# following count of page hits: +# +# 1,103 "Eastern Summer Time" AND domain:au +# 971 "Australian Eastern Summer Time" AND domain:au +# 613 "Eastern Daylight Time" AND domain:au +# 127 "Australian Eastern Daylight Time" AND domain:au +# +# Here "Summer" seems quite a bit more popular than "Daylight", +# particularly when we know the time zone is Australian and not US, +# say. The "Australian" prefix seems to be popular for Eastern Summer +# Time, but unpopular for Eastern Daylight Time. +# +# For abbreviations, tools like AltaVista are less useful because of +# ambiguity. Many hits are not really time zones, unfortunately, and +# many hits denote US time zones and not Australian ones. But here +# are the hit counts anyway: +# +# 161,304 "EST" and domain:au +# 25,156 "EDT" and domain:au +# 18,263 "AEST" and domain:au +# 10,416 "AEDT" and domain:au +# +# 14,538 "CST" and domain:au +# 5,728 "CDT" and domain:au +# 176 "ACST" and domain:au +# 29 "ACDT" and domain:au +# +# 7,539 "WST" and domain:au +# 68 "AWST" and domain:au +# +# This data suggest that Australians tend to omit the "A" prefix in +# practice. The situation for "ST" versus "DT" is less clear, given +# the ambiguities involved. +# +# * How do Australians feel about the abbreviations in the tz database? +# +# If you just count Australians on this list, I count 2 in favor and 3 +# against. One of the "against" votes (David Keegel) counseled delay, +# saying that both AEST/AEDT and EST/EST are widely used and +# understood in Australia. + +# From Paul Eggert (1995-12-19): +# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. +# Mark Prior writes that his newspaper +# reports that NSW's fall 1995 change will occur at 2:00, +# but Robert Elz says it's been 3:00 in Victoria since 1970 +# and perhaps the newspaper's `2:00' is referring to standard time. +# For now we'll continue to assume 2:00s for changes since 1960. + +# From Eric Ulevik (1998-01-05): +# +# Here are some URLs to Australian time legislation.

Mapmakers are free to draw it as they please. +# Reputable mapmakers will simply ensure that every point of land appears on +# the correct side of the IDL, according to the date legally observed there. +# +# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and +# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL +# to the east side of the Phoenix and Line Islands), I suppose that most +# 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.... 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. + +# From Paul Eggert, using references suggested by Oscar van Vlijmen +# (2005-03-20): +# +# The American Practical Navigator (2002) +# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> +# talks only about the 180-degree meridian with respect to ships in +# international waters; it ignores the international date line. diff --git a/servo/static/js/flot/examples/axes-time-zones/tz/backward b/servo/static/js/flot/examples/axes-time-zones/tz/backward new file mode 100755 index 0000000..dc7769f --- /dev/null +++ b/servo/static/js/flot/examples/axes-time-zones/tz/backward @@ -0,0 +1,117 @@ +# <pre> +# This file is in the public domain, so clarified as of +# 2009-05-17 by Arthur David Olson. + +# This file provides links between current names for time zones +# and their old names.

There was a photo +# and a sketch map showing some of the sightlines involved. One paragraph +# of the text said: +# +# `An old stone obelisk marking a forgotten terrestrial meridian stands +# beside the river at Kew. In the 18th century, before time and longitude +# was standardised by the Royal Observatory in Greenwich, scholars observed +# this stone and the movement of stars from Kew Observatory nearby. They +# made their calculations and set the time for the Horse Guards and Parliament, +# but now the stone is obscured by scrubwood and can only be seen by walking +# along the towpath within a few yards of it.' +# +# I have a one inch to one mile map of London and my estimate of the stone's +# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should +# be within about +-2". The Ordnance Survey grid reference is TQ172761. +# +# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] + +# From Paul Eggert (1993-11-18): +# +# Howse writes that Britain was the first country to use standard time. +# The railways cared most about the inconsistencies of local mean time, +# and it was they who forced a uniform time on the country. +# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) +# and was popularized by Abraham Follett Osler (1808-1903). +# The first railway to adopt London time was the Great Western Railway +# in November 1840; other railways followed suit, and by 1847 most +# (though not all) railways used London time. On 1847-09-22 the +# Railway Clearing House, an industry standards body, recommended that GMT be +# adopted at all stations as soon as the General Post Office permitted it. +# The transition occurred on 12-01 for the L&NW, the Caledonian, +# and presumably other railways; the January 1848 Bradshaw's lists many +# railways as using GMT. By 1855 the vast majority of public +# clocks in Britain were set to GMT (though some, like the great clock +# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, +# one for local time and one for GMT). The last major holdout was the legal +# system, which stubbornly stuck to local time for many years, leading +# to oddities like polls opening at 08:13 and closing at 16:13. +# The legal system finally switched to GMT when the Statutes (Definition +# of Time) Act took effect; it received the Royal Assent on 1880-08-02. +# +# In the tables below, we condense this complicated story into a single +# transition date for London, namely 1847-12-01. We don't know as much +# about Dublin, so we use 1880-08-02, the legal transition time. + +# From Paul Eggert (2003-09-27): +# Summer Time was first seriously proposed by William Willett (1857-1915), +# a London builder and member of the Royal Astronomical Society +# who circulated a pamphlet ``The Waste of Daylight'' (1907) +# that proposed advancing clocks 20 minutes on each of four Sundays in April, +# and retarding them by the same amount on four Sundays in September. +# A bill was drafted in 1909 and introduced in Parliament several times, +# but it met with ridicule and opposition, especially from farming interests. +# Later editions of the pamphlet proposed one-hour summer time, and +# it was eventually adopted as a wartime measure in 1916. +# See: Summer Time Arrives Early, The Times (2000-05-18). +# A monument to Willett was unveiled on 1927-05-21, in an open space in +# a 45-acre wood near Chislehurst, Kent that was purchased by popular +# subscription and open to the public. On the south face of the monolith, +# designed by G. W. Miller, is the...William Willett Memorial Sundial, +# which is permanently set to Summer Time. + +# From Winston Churchill (1934-04-28): +# It is one of the paradoxes of history that we should owe the boon of +# summer time, which gives every year to the people of this country +# between 160 and 170 hours more daylight leisure, to a war which +# plunged Europe into darkness for four years, and shook the +# foundations of civilization throughout the world. +# -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> +# "A Silent Toast to William Willett", Pictorial Weekly +# </a> + +# From Paul Eggert (1996-09-03): +# The OED Supplement says that the English originally said ``Daylight Saving'' +# when they were debating the adoption of DST in 1908; but by 1916 this +# term appears only in quotes taken from DST's opponents, whereas the +# proponents (who eventually won the argument) are quoted as using ``Summer''. + +# From Arthur David Olson (1989-01-19): +# +# A source at the British Information Office in New York avers that it's +# known as "British" Summer Time in all parts of the United Kingdom. + +# Date: 4 Jan 89 08:57:25 GMT (Wed) +# From: Jonathan Leffler +# [British Summer Time] is fixed annually by Act of Parliament. +# If you can predict what Parliament will do, you should be in +# politics making a fortune, not computing. + +# From Chris Carrier (1996-06-14): +# I remember reading in various wartime issues of the London Times the +# acronym BDST for British Double Summer Time.

(From +# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been +# able to find if Jan Mayen used a different time zone (e.g. -0100) +# before 1930. Jan Mayen has only been "inhabitated" since 1921 by +# Norwegian meteorologists and maybe used the same time as Norway ever +# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since +# before 1895, and therefore probably changed the local time somewhere +# between 1895 and 1925 (inclusive). + +# From Paul Eggert (2001-05-01): +# +# Actually, Jan Mayen was never occupied by Germany during World War II, +# so it must have diverged from Oslo time during the war, as Oslo was +# keeping Berlin time. +# +# <http://home.no.net/janmayen/history.htm> says that the meteorologists +# burned down their station in 1940 and left the island, but returned in +# 1941 with a small Norwegian garrison and continued operations despite +# frequent air ttacks from Germans. In 1943 the Americans established a +# radiolocating station on the island, called "Atlantic City". Possibly +# the UTC offset changed during the war, but I think it unlikely that +# Jan Mayen used German daylight-saving rules. +# +# Svalbard is more complicated, as it was raided in August 1941 by an +# Allied party that evacuated the civilian population to England (says +# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ +# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were +# expelled on 1942-05-14. However, small parties of Germans did return, +# and according to Wilhelm Dege's book "War North of 80" (1954) +# <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html> +# the German armed forces at the Svalbard weather station code-named +# Haudegen did not surrender to the Allies until September 1945. +# +# All these events predate our cutoff date of 1970. Unless we can +# come up with more definitive info about the timekeeping during the +# war years it's probably best just do...the following for now: +Link Europe/Oslo Arctic/Longyearbyen + +# Poland +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule Poland 1918 1919 - Sep 16 2:00s 0 - +Rule Poland 1919 only - Apr 15 2:00s 1:00 S +Rule Poland 1944 only - Apr 3 2:00s 1:00 S +# Whitman gives 1944 Nov 30; go with Shanks & Pottenger. +Rule Poland 1944 only - Oct 4 2:00 0 - +# For 1944-1948 Whitman gives the previous day; go with Shanks & Pottenger. +Rule Poland 1945 only - Apr 29 0:00 1:00 S +Rule Poland 1945 only - Nov 1 0:00 0 - +# For 1946 on the source is Kazimierz Borkowski, +# Torun Center for Astronomy, Dept. of Radio Astronomy, Nicolaus Copernicus U., +# <http://www.astro.uni.torun.pl/~kb/Artykuly/U-PA/Czas2.htm#tth_tAb1> +# Thanks to Przemyslaw Augustyniak (2005-05-28) for this reference. +# He also gives these further references: +# Mon Pol nr 13, poz 162 (1995) <http://www.abc.com.pl/serwis/mp/1995/0162.htm> +# Druk nr 2180 (2003) <http://www.senat.gov.pl/k5/dok/sejm/053/2180.pdf> +Rule Poland 1946 only - Apr 14 0:00s 1:00 S +Rule Poland 1946 only - Oct 7 2:00s 0 - +Rule Poland 1947 only - May 4 2:00s 1:00 S +Rule Poland 1947 1949 - Oct Sun>=1 2:00s 0 - +Rule Poland 1948 only - Apr 18 2:00s 1:00 S +Rule Poland 1949 only - Apr 10 2:00s 1:00 S +Rule Poland 1957 only - Jun 2 1:00s 1:00 S +Rule Poland 1957 1958 - Sep lastSun 1:00s 0 - +Rule Poland 1958 only - Mar 30 1:00s 1:00 S +Rule Poland 1959 only - May 31 1:00s 1:00 S +Rule Poland 1959 1961 - Oct Sun>=1 1:00s 0 - +Rule Poland 1960 only - Apr 3 1:00s 1:00 S +Rule Poland 1961 1964 - May lastSun 1:00s 1:00 S +Rule Poland 1962 1964 - Sep lastSun 1:00s 0 - +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Europe/Warsaw 1:24:00 - LMT 1880 + 1:24:00 - WMT 1915 Aug 5 # Warsaw Mean Time + 1:00 C-Eur CE%sT 1918 Sep 16 3:00 + 2:00 Poland EE%sT 1922 Jun + 1:00 Poland CE%sT 1940 Jun 23 2:00 + 1:00 C-Eur CE%sT 1944 Oct + 1:00 Poland CE%sT 1977 + 1:00 W-Eur CE%sT 1988 + 1:00 EU CE%sT + +# Portugal +# +# From Rui Pedro Salgueiro (1992-11-12): +# Portugal has recently (September, 27) changed timezone +# (from WET to MET or CET) to harmonize with EEC. +# +# Martin Bruckmann (1996-02-29) reports via Peter Ilieve +# that Portugal is reverting to 0:00 by not moving its clocks this spring. +# The new Prime Minister was fed up with getting up in the dark in the winter. +# +# From Paul Eggert (1996-11-12): +# IATA SSIM (1991-09) reports several 1991-09 and 1992-09 transitions +# at 02:00u, not 01:00u.

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. + +# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S +Rule NT_YK 1918 only - Apr 14 2:00 1:00 D +Rule NT_YK 1918 only - Oct 27 2:00 0 S +Rule NT_YK 1919 only - May 25 2:00 1:00 D +Rule NT_YK 1919 only - Nov 1 0:00 0 S +Rule NT_YK 1942 only - Feb 9 2:00 1:00 W # War +Rule NT_YK 1945 only - Aug 14 23:00u 1:00 P # Peace +Rule NT_YK 1945 only - Sep 30 2:00 0 S +Rule NT_YK 1965 only - Apr lastSun 0:00 2:00 DD +Rule NT_YK 1965 only - Oct lastSun 2:00 0 S +Rule NT_YK 1980 1986 - Apr lastSun 2:00 1:00 D +Rule NT_YK 1980 2006 - Oct lastSun 2:00 0 S +Rule NT_YK 1987 2006 - Apr Sun>=1 2:00 1:00 D +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +# aka Panniqtuuq +Zone America/Pangnirtung 0 - zzz 1921 # trading post est. + -4:00 NT_YK A%sT 1995 Apr Sun>=1 2:00 + -5:00 Canada E%sT 1999 Oct 31 2:00 + -6:00 Canada C%sT 2000 Oct 29 2:00 + -5:00 Canada E%sT +# formerly Frobisher Bay +Zone America/Iqaluit 0 - zzz 1942 Aug # Frobisher Bay est. + -5:00 NT_YK E%sT 1999 Oct 31 2:00 + -6:00 Canada C%sT 2000 Oct 29 2:00 + -5:00 Canada E%sT +# aka Qausuittuq +Zone America/Resolute 0 - zzz 1947 Aug 31 # Resolute founded + -6:00 NT_YK C%sT 2000 Oct 29 2:00 + -5:00 - EST 2001 Apr 1 3:00 + -6:00 Canada C%sT 2006 Oct 29 2:00 + -5:00 - EST 2007 Mar 11 3:00 + -6:00 Canada C%sT +# aka Kangiqiniq +Zone America/Rankin_Inlet 0 - zzz 1957 # Rankin Inlet founded + -6:00 NT_YK C%sT 2000 Oct 29 2:00 + -5:00 - EST 2001 Apr 1 3:00 + -6:00 Canada C%sT +# aka Iqaluktuuttiaq +Zone America/Cambridge_Bay 0 - zzz 1920 # trading post est.? + -7:00 NT_YK M%sT 1999 Oct 31 2:00 + -6:00 Canada C%sT 2000 Oct 29 2:00 + -5:00 - EST 2000 Nov 5 0:00 + -6:00 - CST 2001 Apr 1 3:00 + -7:00 Canada M%sT +Zone America/Yellowknife 0 - zzz 1935 # Yellowknife founded? + -7:00 NT_YK M%sT 1980 + -7:00 Canada M%sT +Zone America/Inuvik 0 - zzz 1953 # Inuvik founded + -8:00 NT_YK P%sT 1979 Apr lastSun 2:00 + -7:00 NT_YK M%sT 1980 + -7:00 Canada M%sT +Zone America/Whitehorse -9:00:12 - LMT 1900 Aug 20 + -9:00 NT_YK Y%sT 1966 Jul 1 2:00 + -8:00 NT_YK P%sT 1980 + -8:00 Canada P%sT +Zone America/Dawson -9:17:40 - LMT 1900 Aug 20 + -9:00 NT_YK Y%sT 1973 Oct 28 0:00 + -8:00 NT_YK P%sT 1980 + -8:00 Canada P%sT + + +############################################################################### + +# 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.

BOT # Bolivia Time + +# Brazil + +# From Paul Eggert (1993-11-18): +# The mayor of Rio recently attempted to change the time zone rules +# just in his city, in order to leave more summer time for the tourist trade. +# The rule change lasted only part of the day; +# the federal government refused to follow the city's rules, and business +# was in a chaos, so the mayor backed down that afternoon. + +# From IATA SSIM (1996-02): +# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS), +# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ), +# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO), +# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL]. +# [The last three states are new to this issue of the IATA SSIM.] + +# From Gwillim Law (1996-10-07): +# Geography, history (Tocantins was part of Goias until 1989), and other +# sources of time zone information lead me to believe that AL, SE, and TO were +# always in BR1, and so the only change was whether or not they observed DST.... +# The earliest issue of the SSIM I have is 2/91. Each issue from then until +# 9/95 says that DST is observed only in the ten states I quoted from 9/95, +# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 +# (UTC-4).... The other two time zones given for Brazil are BR3, which is +# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is +# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's +# become part of the state of Pernambuco). The boundary between BR1 and BR2 +# has never been clearly stated. They've simply been called East and West. +# However, some conclusions can be drawn from another IATA manual: the Airline +# Coding Directory, which lists close to 400 airports in Brazil. For each +# airport it gives a time zone which is coded to the SSIM. From that +# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE), +# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do +# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST. + +# From Marcos Tadeu (1998-09-27): +# <a href="http://pcdsh01.on.br/verao1.html"> +# Brazilian official page +# </a> + +# From Jesper Norgaard (2000-11-03): +# [For an official list of which regions in Brazil use which time zones, see:] +# http://pcdsh01.on.br/Fusbr.htm +# http://pcdsh01.on.br/Fusbrhv.htm + +# From Celso Doria via David Madeo (2002-10-09): +# The reason for the delay this year has to do with elections in Brazil. +# +# Unlike in the United States, elections in Brazil are 100% computerized and +# the results are known almost immediately. Yesterday, it was the first +# round of the elections when 115 million Brazilians voted for President, +# Governor, Senators, Federal Deputies, and State Deputies. Nobody is +# counting (or re-counting) votes anymore and we know there will be a second +# round for the Presidency and also for some Governors. The 2nd round will +# take place on October 27th. +# +# The reason why the DST will only begin November 3rd is that the thousands +# of electoral machines used cannot have their time changed, and since the +# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM, +# the Government decided to postpone DST, instead of changing the Constitution +# (maybe, for the next elections, it will be possible to change the clock)... + +# From Rodrigo Severo (2004-10-04): +# It's just the biannual change made necessary by the much hyped, supposedly +# modern Brazilian eletronic voting machines which, apparently, can't deal +# with a time change between the first and the second rounds of the elections. + +# From Steffen Thorsen (2007-09-20): +# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00: +# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975 + +# From Paul Schulze (2008-06-24): +# ...by law number 11.662 of April 24, 2008 (published in the "Diario +# Oficial da Uniao"...) in Brazil there are changes in the timezones, +# effective today (00:00am at June 24, 2008) as follows: +# +# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the +# part of the Amazonas state that had this timezone now being put to the +# timezone UTC+4 +# b) The whole Para state now is put at timezone UTC+3, instead of just +# part of it, as was before. +# +# This change follows a proposal of senator Tiao Viana of Acre state, that +# proposed it due to concerns about open television channels displaying +# programs inappropriate to youths in the states that had the timezone +# UTC+5 too early in the night.
