11# From Paul Eggert (2018-05-27):
12#
13# Unless otherwise specified, the source for data through 1990 is:
14# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
15# San Diego: ACS Publications, Inc. (2003).
16# Unfortunately this book contains many errors and cites no sources.
17#
18# Many years ago Gwillim Law wrote that a good source
19# for time zone data was the International Air Transport
20# Association's Standard Schedules Information Manual (IATA SSIM),
21# published semiannually.  Law sent in several helpful summaries
22# of the IATA's data after 1990.  Except where otherwise noted,
23# IATA SSIM is the source for entries after 1990.
24#
25# Another source occasionally used is Edward W. Whitman, World Time Differences,
26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27# I found in the UCLA library.
28#
29# For data circa 1899, a common source is:
30# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
31# https://www.jstor.org/stable/1774359
32#
33# A reliable and entertaining source about time zones is
34# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
35#
36# European-style abbreviations are commonly used along the Mediterranean.
37# For sub-Saharan Africa abbreviations were less standardized.
38# Previous editions of this database used WAT, CAT, SAT, and EAT
39# for UT +00 through +03, respectively,
40# but in 1997 Mark R V Murray reported that
41# 'SAST' is the official abbreviation for +02 in the country of South Africa,
42# 'CAT' is commonly used for +02 in countries north of South Africa, and
43# 'WAT' is probably the best name for +01, as the common phrase for
44# the area that includes Nigeria is "West Africa".
45#
46# To summarize, the following abbreviations seemed to have some currency:
47#	 +00	GMT	Greenwich Mean Time
48#	 +02	CAT	Central Africa Time
49#	 +02	SAST	South Africa Standard Time
50# and Murray suggested the following abbreviation:
51#	 +01	WAT	West Africa Time
52# Murray's suggestion seems to have caught on in news reports and the like.
53# I vaguely recall 'WAT' also being used for -01 in the past but
54# cannot now come up with solid citations.
55#
56# I invented the following abbreviations in the 1990s:
57#	 +02	WAST	West Africa Summer Time
58#	 +03	CAST	Central Africa Summer Time
59#	 +03	SAST	South Africa Summer Time
60#	 +03	EAT	East Africa Time
61# 'EAT' seems to have caught on and is in current timestamps, and though
62# the other abbreviations are rarer and are only in past timestamps,
63# they are paired with better-attested non-DST abbreviations.
64# Corrections are welcome.

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

558# Follow Thorsen on DST in 1982/1983, instead of Shanks & Pottenger.

561# According to
562# http://www.lexpress.mu/display_article.php?news_id=111216
563# (in French), Mauritius will start and end their DST a few days earlier
564# than previously announced (2008-11-01 to 2009-03-31).  The new start
565# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
566# given, but it is probably at either 2 or 3 wall clock time).
567#
568# A little strange though, since the article says that they moved the date
569# to align itself with Europe and USA which also change time on that date,
570# but that means they have not paid attention to what happened in
571# USA/Canada last year (DST ends first Sunday in November). I also wonder
572# why that they end on a Friday, instead of aligning with Europe which
573# changes two days later.

1161# From Gwillim Law (2005-04-30):
1162# My correspondent, Risto Nykänen, has alerted me to another adoption of DST,
1163# this time in Tunisia.  According to Yahoo France News
1164# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
1165# and dated 2005-04-26, "Tunisia has decided to advance its official time by
1166# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
1167# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
1168# Saturday."  (My translation)

1203# From Arthur David Olson (2009-03-18):
1204# The Tunis Afrique Presse News Agency notice contains this: "This measure is
1205# due to the fact that the fasting month of Ramadan coincides with the period
1206# concerned by summer time.  Therefore, the standard time will be kept
1207# unchanged the whole year long."  So foregoing DST seems to be an exception
1208# (albeit one that may be repeated in the future).
1209
1210# From Alexander Krivenyshev (2010-03-27):
1211# According to some news reports Tunis confirmed not to use DST in 2010

1214# "The Tunisian government has decided to abandon DST, which was scheduled on
1215# Sunday...
1216# Tunisian authorities had suspended the DST for the first time last year also
1217# coincided with the month of Ramadan..."
