9# From Paul Eggert (2017-02-20):
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
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.

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.

532# According to

534# (in French), Mauritius will start and end their DST a few days earlier
535# than previously announced (2008-11-01 to 2009-03-31). The new start
536# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
537# given, but it is probably at either 2 or 3 wall clock time).
538#
539# A little strange though, since the article says that they moved the date
540# to align itself with Europe and USA which also change time on that date,
541# but that means they have not paid attention to what happened in
542# USA/Canada last year (DST ends first Sunday in November). I also wonder
543# why that they end on a Friday, instead of aligning with Europe which
544# changes two days later.

798# From Milamber (2015-06-08):
799# (Google Translation) The hour will thus be delayed 60 minutes
800# Sunday, June 14 at 3:00, the ministry said in a statement, adding
801# that the time will be advanced again 60 minutes Sunday, July 19,
802# 2015 at 2:00. The move comes under 2.12.126 Decree of 26 Jumada I
803# 1433 (18 April 2012) and the decision of the Head of Government of
804# 16 N. 3-29-15 Chaaban 1435 (4 June 2015).

812# [The gov.ma announcement] would (probably) make the switch on 2015-07-19 go
