Changes affecting current and future time stamps
Turks & Caicos' switch from US eastern time to UTC-4 year-round
did not occur on 2014-11-02 at 02:00. It's currently scheduled
for 2015-11-01 at 02:00. (Thanks to Chris Walton.)
Changes affecting past time stamps
Many pre-1989 time stamps have been corrected for Asia/Seoul and
Asia/Pyongyang, based on sources for the Korean-language Wikipedia
entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no
longer guess that Pyongyang mimicked Seoul time after World War II,
as this is politically implausible.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
Indian/Mayotte.
Changes affecting commentary
The commentary is less enthusiastic about Shanks as a source,
and is more careful to distinguish UT from UTC.

# From Paul Eggert (2014-10-31):
|
|
#
|
|
# Unless otherwise specified, the source for data through 1990 is:
|
|
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
|
|
# San Diego: ACS Publications, Inc. (2003).
|
|
# Unfortunately this book contains many errors and cites no sources.
|
|
#
|
|
# 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,
|
|
# IATA SSIM is the source for entries after 1990.
|
|
#
|
|
# 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.
|
|
#
|
|
# For data circa 1899, a common source is:
|
|
# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
|
|
# http://www.jstor.org/stable/1774359
|
|
#
|
|
# 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; corrections are welcome!
|
|
# 2:00 WAST West Africa Summer Time
|
|
# 2:30 BEAT British East Africa Time (no longer used)
|
|
# 2:45 BEAUT British East Africa Unified Time (no longer used)

# From Abdelrahman Hassan (2007-09-06):
|
|
# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
|
|
# than the year of the Gregorian calendar, Ramadan shifts earlier each
|
|
# year. This year it will be observed September 13 (September is quite
|
|
# hot in Egypt), and the idea is to make fasting easier for workers by
|
|
# shifting business hours one hour out of daytime heat. Consequently,
|
|
# unless discontinued, next DST may end Thursday 28 August 2008.

# From Paul Eggert (2014-06-04):

|
# Sarah El Deeb and Lee Keath of AP report that the Egyptian government says

# the change is because of blackouts in Cairo, even though Ahram Online (cited

|
|
# A little strange though, since the article says that they moved the date

# From Gwillim Law (2005-04-30):
|
|
# My correspondent, Risto Nykänen, has alerted me to another adoption of DST,
|
|
# this time in Tunisia. According to Yahoo France News
|
|
# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
|
|
# and dated 2005-04-26, "Tunisia has decided to advance its official time by
|
|
# one hour, starting on Sunday, May 1. Henceforth, Tunisian time will be
|
|
# UTC+2 instead of UTC+1. The change will take place at 23:00 UTC next
|
|
# Saturday." (My translation)

# La Presse, the first national daily newspaper ...
|
|

|
|
# ... DST for 2005: on: Sun May 1 0h standard time, off: Fri Sept. 30,
|
|
# 1h standard time.

|
|
# From Atef Loukil (2006-03-28):
|
|
# The daylight saving time will be the same each year:
|
|
# Beginning : the last Sunday of March at 02:00
|
|
# Ending : the last Sunday of October at 03:00 ...

|
|
# From Arthur David Olson (2009-03-18):
|
|
# The Tunis Afrique Presse News Agency notice contains this: "This measure is
|
|
# due to the fact that the fasting month of Ramadan coincides with the period
|
|
# concerned by summer time. Therefore, the standard time will be kept
|
|
# unchanged the whole year long." So foregoing DST seems to be an exception
|
|
# (albeit one that may be repeated in the future).
|
|
|
|
# From Alexander Krivenyshev (2010-03-27):
|
|
# According to some news reports Tunis confirmed not to use DST in 2010
|
|
#
|
|
# (translation):
|
|
# "The Tunisian government has decided to abandon DST, which was scheduled on
|
|
# Sunday...
|
|
# Tunisian authorities had suspended the DST for the first time last year also
|
|
# coincided with the month of Ramadan..."
