9# From Paul Eggert (2017-04-09):
10#
11# Unless otherwise specified, the source for data through 1990 is:
12# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13# San Diego: ACS Publications, Inc. (2003).
14# Unfortunately this book contains many errors and cites no sources.
15#
16# Many years ago Gwillim Law wrote that a good source
17# for time zone data was the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually.  Law sent in several helpful summaries
20# of the IATA's data after 1990.  Except where otherwise noted,
21# IATA SSIM is the source for entries after 1990.
22#
23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.
26#
27# For data circa 1899, a common source is:
28# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
29# https://www.jstor.org/stable/1774359
30#
31# A reliable and entertaining source about time zones is
32# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
33#
34# European-style abbreviations are commonly used along the Mediterranean.
35# For sub-Saharan Africa abbreviations were less standardized.
36# Previous editions of this database used WAT, CAT, SAT, and EAT
37# for UT +00 through +03, respectively,
38# but in 1997 Mark R V Murray reported that
39# 'SAST' is the official abbreviation for +02 in the country of South Africa,
40# 'CAT' is commonly used for +02 in countries north of South Africa, and
41# 'WAT' is probably the best name for +01, as the common phrase for
42# the area that includes Nigeria is "West Africa".
43#
44# To summarize, the following abbreviations seemed to have some currency:
45#	 +00	GMT	Greenwich Mean Time
46#	 +02	CAT	Central Africa Time
47#	 +02	SAST	South Africa Standard Time
48# and Murray suggested the following abbreviation:
49#	 +01	WAT	West Africa Time
50# Murray's suggestion seems to have caught on in news reports and the like.
51# I vaguely recall 'WAT' also being used for -01 in the past but
52# cannot now come up with solid citations.
53#
54# I invented the following abbreviations; corrections are welcome!
55#	 +02	WAST	West Africa Summer Time (no longer used)
56#	 +03	CAST	Central Africa Summer Time (no longer used)
57#	 +03	SAST	South Africa Summer Time (no longer used)
58#	 +03	EAT	East Africa Time
59# 'EAT' also seems to have caught on; the others are rare but are paired
60# with better-attested non-DST abbreviations.

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

550# According to

552# (in French), Mauritius will start and end their DST a few days earlier
553# than previously announced (2008-11-01 to 2009-03-31).  The new start
554# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
555# given, but it is probably at either 2 or 3 wall clock time).
556#
557# A little strange though, since the article says that they moved the date
558# to align itself with Europe and USA which also change time on that date,
559# but that means they have not paid attention to what happened in
560# USA/Canada last year (DST ends first Sunday in November). I also wonder
561# why that they end on a Friday, instead of aligning with Europe which
562# changes two days later.

752# last Sunday of September (September 30, 2012)

757# From Arthur David Olson (2012-03-10):
758# The infomediaire.ma source indicates that the system is to be in
759# effect every year. It gives 03H00 as the "fall back" time of day;
760# it lacks a "spring forward" time of day; assume 2:00 XXX.
761# Wait on specifying the Ramadan exception for details about
762# start date, start time of day, end date, and end time of day XXX.

776# Pursuant to Decree No. 2-12-126 issued on 26 Jumada (I) 1433 (April 18,
777# 2012) and in accordance with the order of Mr. President of the

780# of the legal time of the Kingdom (GMT) from Friday, July 20, 2012 until
781# Monday, August 20, 2012.  So the time will be delayed by 60 minutes from

798# Morocco extends DST by one month, on very short notice, just 1 day

819# that the time will be advanced again 60 minutes Sunday, July 19,

830# [The gov.ma announcement] would (probably) make the switch on 2015-07-19 go
831# from 03:00 to 04:00 rather than from 02:00 to 03:00, as in the patch....
832# I think the patch is correct and the quoted text is wrong; the text in
833# <https://lnt.ma/le-maroc-reculera-dune-heure-le-dimanche-14-juin/> agrees

835
836# From Paul Eggert (2015-06-08):
837# For now, guess that later spring and fall transitions will use 2015's rules,
838# and guess that Morocco will switch to standard time at 03:00 the last
839# Sunday before Ramadan, and back to DST at 02:00 the first Sunday after
840# Ramadan.  To implement this, transition dates for 2016 through 2037 were

1186# and dated 2005-04-26, "Tunisia has decided to advance its official time by
1187# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be

1224# From Arthur David Olson (2009-03-18):
1225# The Tunis Afrique Presse News Agency notice contains this: "This measure is
1226# due to the fact that the fasting month of Ramadan coincides with the period
1227# concerned by summer time.  Therefore, the standard time will be kept
1228# unchanged the whole year long."  So foregoing DST seems to be an exception
1229# (albeit one that may be repeated in the future).
