10 # From Paul Eggert (2006-03-22):
12 # A good source for time zone historical data outside the U.S. is
13 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14 # San Diego: ACS Publications, Inc. (2003).
16 # Gwillim Law writes that a good source
17 # for recent time zone data is 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.
22 # Except where otherwise noted, Shanks & Pottenger is the source for
23 # entries through 1990, and IATA SSIM is the source for entries afterwards.
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 # A reliable and entertaining source about time zones is
30 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
32 # Previous editions of this database used WAT, CAT, SAT, and EAT
33 # for +0:00 through +3:00, respectively,
34 # but Mark R V Murray reports that
35 # `SAST' is the official abbreviation for +2:00 in the country of South Africa,
36 # `CAT' is commonly used for +2:00 in countries north of South Africa, and
37 # `WAT' is probably the best name for +1:00, as the common phrase for
38 # the area that includes Nigeria is ``West Africa''.
39 # He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
41 # To make things confusing, `WAT' seems to have been used for -1:00 long ago;
42 # I'd guess that this was because people needed _some_ name for -1:00,
43 # and at the time, far west Africa was the only major land area in -1:00.
44 # This usage is now obsolete, as the last use of -1:00 on the African
45 # mainland seems to have been 1976 in Western Sahara.
47 # To summarize, the following abbreviations seem to have some currency:
48 # -1:00 WAT West Africa Time (no longer used)
49 # 0:00 GMT Greenwich Mean Time
50 # 2:00 CAT Central Africa Time
51 # 2:00 SAST South Africa Standard Time
52 # and Murray suggests the following abbreviation:
53 # 1:00 WAT West Africa Time
54 # I realize that this leads to `WAT' being used for both -1:00 and 1:00
55 # for times before 1976, but this is the best I can think of
56 # until we get more information.
58 # I invented the following abbreviations; corrections are welcome!
59 # 2:00 WAST West Africa Summer Time
60 # 2:30 BEAT British East Africa Time (no longer used)
61 # 2:44:45 BEAUT British East Africa Unified Time (no longer used)
62 # 3:00 CAST Central Africa Summer Time (no longer used)
63 # 3:00 SAST South Africa Summer Time (no longer used)
64 # 3:00 EAT East Africa Time
65 # 4:00 EAST East Africa Summer Time (no longer used)

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

455 # (in French), Mauritius will start and end their DST a few days earlier
456 # than previously announced (2008-11-01 to 2009-03-31). The new start
457 # date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
458 # given, but it is probably at either 2 or 3 wall clock time).
460 # A little strange though, since the article says that they moved the date
461 # to align itself with Europe and USA which also change time on that date,
462 # but that means they have not paid attention to what happened in
463 # USA/Canada last year (DST ends first Sunday in November). I also wonder

493 # the last Sunday of March the following year. The summer time for the
