4 # This data is by no means authoritative; if you think you know better,
5 # go ahead and edit the file (and please send any changes to
6 # tz@elsie.nci.nih.gov for general use in the future).
8 # From Paul Eggert (1999-03-22):
9 #
10 # A good source for time zone historical data outside the U.S. is
11 # Thomas G. Shanks, The International Atlas (5th edition),
12 # San Diego: ACS Publications, Inc. (1999).
13 #
14 # Gwillim Law writes that a good source
15 # for recent time zone data is the International Air Transport
16 # Association's Standard Schedules Information Manual (IATA SSIM),
17 # published semiannually. Law sent in several helpful summaries
18 # of the IATA's data after 1990.
19 #
20 # Except where otherwise noted, Shanks is the source for entries through 1990,
21 # and 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 # A reliable and entertaining source about time zones is
28 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
29 #
30 # Previous editions of this database used WAT, CAT, SAT, and EAT
31 # for +0:00 through +3:00, respectively,
32 # but Mark R V Murray reports that
33 # `SAST' is the official abbreviation for +2:00 in the country of South Africa,
34 # `CAT' is commonly used for +2:00 in countries north of South Africa, and
35 # `WAT' is probably the best name for +1:00, as the common phrase for
36 # the area that includes Nigeria is ``West Africa''.
37 # He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
38 #
39 # To make things confusing, `WAT' seems to have been used for -1:00 long ago;
40 # I'd guess that this was because people needed _some_ name for -1:00,
41 # and at the time, far west Africa was the only major land area in -1:00.
42 # This usage is now obsolete, as the last use of -1:00 on the African
43 # mainland seems to have been 1976 in Western Sahara.
44 #
45 # To summarize, the following abbreviations seem to have some currency:
46 # -1:00 WAT West Africa Time (no longer used)
47 # 0:00 GMT Greenwich Mean Time
48 # 2:00 CAT Central Africa Time
49 # 2:00 SAST South Africa Standard Time
50 # and Murray suggests the following abbreviation:
51 # 1:00 WAT West Africa Time
52 # I realize that this leads to `WAT' being used for both -1:00 and 1:00
53 # for times before 1976, but this is the best I can think of
54 # until we get more information.
55 #
56 # I invented the following abbreviations; corrections are welcome!
57 # 2:00 WAST West Africa Summer Time
58 # 2:30 BEAT British East Africa Time (no longer used)
59 # 2:44:45 BEAUT British East Africa Unified Time (no longer used)
60 # 3:00 CAST Central Africa Summer Time (no longer used)
61 # 3:00 SAST South Africa Summer Time (no longer used)
62 # 3:00 EAT East Africa Time
63 # 4:00 EAST East Africa Summer Time (no longer used)
