11 # From Paul Eggert (2018-05-27):
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.
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.
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.
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
33 # A reliable and entertaining source about time zones is
34 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
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".
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.
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.

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

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

871 # Following the announcement by the Moroccan government, the switch to
872 # GMT time will take place on Sunday, April 19, 2020 from 3 a.m. and

877 # From Milamber (2020-05-31)
878 # In Morocco (where I live), the end of Ramadan (Arabic month) is followed by
879 # the Eid al-Fitr, and concretely it's 1 or 2 day offs for the people (with
880 # traditional visiting of family, big lunches/dinners, etc.). So for this
881 # year the astronomical calculations don't include the following 2 days off in
882 # the calc. These 2 days fall in a Sunday/Monday, so it's not acceptable by
883 # people to have a time shift during these 2 days off. Perhaps you can modify
884 # the (predicted) rules for next years: if the end of Ramadan is a (probable)
885 # Friday or Saturday (and so the 2 days off are on a weekend), the next time
886 # shift will be the next weekend.
888 # From Paul Eggert (2020-05-31):
889 # For now, guess that in the future Morocco will fall back at 03:00
890 # the last Sunday before Ramadan, and spring forward at 02:00 the
891 # first Sunday after two days after Ramadan. To implement this,
892 # transition dates and times for 2019 through 2087 were determined by
893 # running the following program under GNU Emacs 26.3. (This algorithm
894 # also produces the correct transition dates for 2016 through 2018,
895 # though the times differ due to Morocco's time zone change in 2018.)
