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# For the 1911/1912 establishment of standard time in French possessions, see:
34# Société Française de Physique, Recueil de constantes physiques (1913),
35# page 752, 18b.
36#
37# European-style abbreviations are commonly used along the Mediterranean.
38# For sub-Saharan Africa abbreviations were less standardized.
39# Previous editions of this database used WAT, CAT, SAT, and EAT
40# for UT +00 through +03, respectively,
41# but in 1997 Mark R V Murray reported that
42# 'SAST' is the official abbreviation for +02 in the country of South Africa,
43# 'CAT' is commonly used for +02 in countries north of South Africa, and
44# 'WAT' is probably the best name for +01, as the common phrase for
45# the area that includes Nigeria is "West Africa".
46#
47# To summarize, the following abbreviations seemed to have some currency:
48#	 +00	GMT	Greenwich Mean Time
49#	 +02	CAT	Central Africa Time
50#	 +02	SAST	South Africa Standard Time
51# and Murray suggested the following abbreviation:
52#	 +01	WAT	West Africa Time
53# Murray's suggestion seems to have caught on in news reports and the like.
54# I vaguely recall 'WAT' also being used for -01 in the past but
55# cannot now come up with solid citations.
56#
57# I invented the following abbreviations in the 1990s:
58#	 +02	WAST	West Africa Summer Time
59#	 +03	CAST	Central Africa Summer Time
60#	 +03	SAST	South Africa Summer Time
61#	 +03	EAT	East Africa Time
62# 'EAT' seems to have caught on and is in current timestamps, and though
63# the other abbreviations are rarer and are only in past timestamps,
64# they are paired with better-attested non-DST abbreviations.
65# Corrections are welcome.

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

523# According to

525# (in French), Mauritius will start and end their DST a few days earlier
526# than previously announced (2008-11-01 to 2009-03-31).  The new start
527# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
528# given, but it is probably at either 2 or 3 wall clock time).
529#
530# A little strange though, since the article says that they moved the date
531# to align itself with Europe and USA which also change time on that date,
532# but that means they have not paid attention to what happened in
533# USA/Canada last year (DST ends first Sunday in November). I also wonder
534# why that they end on a Friday, instead of aligning with Europe which
535# changes two days later.

729# The infomediaire.ma source indicates that the system is to be in
730# effect every year. It gives 03H00 as the "fall back" time of day;
731# it lacks a "spring forward" time of day; assume 2:00 XXX.
732# Wait on specifying the Ramadan exception for details about
733# start date, start time of day, end date, and end time of day XXX.

833# From Milamber (2020-05-31)
834# In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
835# the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
836# traditional visiting of family, big lunches/dinners, etc.).  So for this
837# year the astronomical calculations don't include the following 2 days off in
838# the calc.  These 2 days fall in a Sunday/Monday, so it's not acceptable by
839# people to have a time shift during these 2 days off.  Perhaps you can modify
840# the (predicted) rules for next years: if the end of Ramadan is a (probable)
841# Friday or Saturday (and so the 2 days off are on a weekend), the next time
842# shift will be the next weekend.

1108# (as Maputo was then called) was dropped daily at 13:00:00 LMT,

1110# Conversely, the newspaper South Africa, 1909-02-09, page 321,

1365# From Gwillim Law (2005-04-30):
1366# My correspondent, Risto Nykänen, has alerted me to another adoption of DST,
1367# this time in Tunisia.  According to Yahoo France News
1368# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
1369# and dated 2005-04-26, "Tunisia has decided to advance its official time by
1370# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
1371# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
1372# Saturday."  (My translation)

1377# ... DST for 2005: on: Sun May 1 0h standard time, off: Fri Sept. 30,
1378# 1h standard time.
1379#
1380# From Atef Loukil (2006-03-28):
1381# The daylight saving time will be the same each year:

1406
1407# From Arthur David Olson (2009-03-18):
1408# The Tunis Afrique Presse News Agency notice contains this: "This measure is
1409# due to the fact that the fasting month of Ramadan coincides with the period
1410# concerned by summer time.  Therefore, the standard time will be kept
1411# unchanged the whole year long."  So foregoing DST seems to be an exception
1412# (albeit one that may be repeated in the future).
1413
1414# From Alexander Krivenyshev (2010-03-27):
1415# According to some news reports Tunis confirmed not to use DST in 2010
1416#
1417# (translation):
1418# "The Tunisian government has decided to abandon DST, which was scheduled on
1419# Sunday...
1420# Tunisian authorities had suspended the DST for the first time last year also
1421# coincided with the month of Ramadan..."
