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# European-style abbreviations are commonly used along the Mediterranean.
34# For sub-Saharan Africa abbreviations were less standardized.
35# Previous editions of this database used WAT, CAT, SAT, and EAT
36# for UT +00 through +03, respectively,
37# but in 1997 Mark R V Murray reported that
38# 'SAST' is the official abbreviation for +02 in the country of South Africa,
39# 'CAT' is commonly used for +02 in countries north of South Africa, and
40# 'WAT' is probably the best name for +01, as the common phrase for
41# the area that includes Nigeria is "West Africa".
42#
43# To summarize, the following abbreviations seemed to have some currency:
44#	 +00	GMT	Greenwich Mean Time
45#	 +02	CAT	Central Africa Time
46#	 +02	SAST	South Africa Standard Time
47# and Murray suggested the following abbreviation:
48#	 +01	WAT	West Africa Time
49# Murray's suggestion seems to have caught on in news reports and the like.
50# I vaguely recall 'WAT' also being used for -01 in the past but
51# cannot now come up with solid citations.
52#
53# I invented the following abbreviations in the 1990s:
54#	 +02	WAST	West Africa Summer Time
55#	 +03	CAST	Central Africa Summer Time
56#	 +03	SAST	South Africa Summer Time
57#	 +03	EAT	East Africa Time
58# 'EAT' seems to have caught on and is in current timestamps, and though
59# the other abbreviations are rarer and are only in past timestamps,
60# they are paired with better-attested non-DST abbreviations.
61# Corrections are welcome.

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

572# According to

574# (in French), Mauritius will start and end their DST a few days earlier
575# than previously announced (2008-11-01 to 2009-03-31).  The new start
576# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
577# given, but it is probably at either 2 or 3 wall clock time).
578#
579# A little strange though, since the article says that they moved the date
580# to align itself with Europe and USA which also change time on that date,
581# but that means they have not paid attention to what happened in
582# USA/Canada last year (DST ends first Sunday in November). I also wonder
583# why that they end on a Friday, instead of aligning with Europe which
584# changes two days later.

759# They have it written in English here:
760# http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view
761#
762# It says there that "Morocco will resume its standard time on July 31,
763# 2011 at midnight." Now they don't say whether they mean midnight of
764# wall clock time (i.e. 11pm UTC), but that's what I would assume. It has
765# also been like that in the past.

884# From Milamber (2020-05-31)
885# In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
886# the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
887# traditional visiting of family, big lunches/dinners, etc.).  So for this
888# year the astronomical calculations don't include the following 2 days off in
889# the calc.  These 2 days fall in a Sunday/Monday, so it's not acceptable by
890# people to have a time shift during these 2 days off.  Perhaps you can modify
891# the (predicted) rules for next years: if the end of Ramadan is a (probable)
892# Friday or Saturday (and so the 2 days off are on a weekend), the next time
893# shift will be the next weekend.
894#
895# From Paul Eggert (2020-05-31):
896# For now, guess that in the future Morocco will fall back at 03:00

899# transition dates and times for 2019 through 2087 were determined by
900# running the following program under GNU Emacs 26.3.  (This algorithm

1462# From Gwillim Law (2005-04-30):
1463# My correspondent, Risto Nykänen, has alerted me to another adoption of DST,
1464# this time in Tunisia.  According to Yahoo France News
1465# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
1466# and dated 2005-04-26, "Tunisia has decided to advance its official time by
1467# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
1468# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
1469# Saturday."  (My translation)

1503
1504# From Arthur David Olson (2009-03-18):
1505# The Tunis Afrique Presse News Agency notice contains this: "This measure is
1506# due to the fact that the fasting month of Ramadan coincides with the period
1507# concerned by summer time.  Therefore, the standard time will be kept
1508# unchanged the whole year long."  So foregoing DST seems to be an exception
1509# (albeit one that may be repeated in the future).
1510
1511# From Alexander Krivenyshev (2010-03-27):
1512# According to some news reports Tunis confirmed not to use DST in 2010
1513#
1514# (translation):
1515# "The Tunisian government has decided to abandon DST, which was scheduled on
1516# Sunday...
1517# Tunisian authorities had suspended the DST for the first time last year also
1518# coincided with the month of Ramadan..."
