11 11 # Unless otherwise specified, the source for data through 1990 is:
12 12 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13 13 # San Diego: ACS Publications, Inc. (2003).
14 14 # Unfortunately this book contains many errors and cites no sources.
15 15 #
16 16 # Many years ago Gwillim Law wrote that a good source
17 17 # for time zone data was the International Air Transport
18 18 # Association's Standard Schedules Information Manual (IATA SSIM),
19 19 # published semiannually. Law sent in several helpful summaries
20 20 # of the IATA's data after 1990. Except where otherwise noted,
21 21 # IATA SSIM is the source for entries after 1990.
22 22 #
23 23 # Another source occasionally used is Edward W. Whitman, World Time Differences,
24 24 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25 25 # I found in the UCLA library.
26 26 #
27 27 # For data circa 1899, a common source is:
28 28 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
29 29 # https://www.jstor.org/stable/1774359
30 30 #
31 31 # A reliable and entertaining source about time zones is
32 32 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
33 33 #
34 34 # European-style abbreviations are commonly used along the Mediterranean.
35 35 # For sub-Saharan Africa abbreviations were less standardized.
36 36 # Previous editions of this database used WAT, CAT, SAT, and EAT
37 37 # for UT +00 through +03, respectively,
38 38 # but in 1997 Mark R V Murray reported that
39 39 # 'SAST' is the official abbreviation for +02 in the country of South Africa,
40 40 # 'CAT' is commonly used for +02 in countries north of South Africa, and
41 41 # 'WAT' is probably the best name for +01, as the common phrase for
42 42 # the area that includes Nigeria is "West Africa".
43 43 #
44 44 # To summarize, the following abbreviations seemed to have some currency:

45 45 # +00 GMT Greenwich Mean Time
46 46 # +02 CAT Central Africa Time
47 47 # +02 SAST South Africa Standard Time
48 48 # and Murray suggested the following abbreviation:
49 49 # +01 WAT West Africa Time
50 50 # Murray's suggestion seems to have caught on in news reports and the like.
51 51 # I vaguely recall 'WAT' also being used for -01 in the past but
52 52 # cannot now come up with solid citations.
53 53 #
54 54 # I invented the following abbreviations; corrections are welcome!
55 -# +02 WAST West Africa Summer Time
55 +# +02 WAST West Africa Summer Time (no longer used)
56 56 # +03 CAST Central Africa Summer Time (no longer used)
57 57 # +03 SAST South Africa Summer Time (no longer used)
58 58 # +03 EAT East Africa Time
59 59 # 'EAT' also seems to have caught on; the others are rare but are paired
60 60 # with better-attested non-DST abbreviations.

227 227 # year. This year it will be observed September 13 (September is quite

229 229 # shifting business hours one hour out of daytime heat. Consequently,

943 962 # The text of the "Namibia Time Act, 1994" is available online at
944 963 # www.lac.org.na/laws/1994/811.pdf
945 964 # and includes this nugget:
946 965 # Notwithstanding the provisions of subsection (2) of section 1, the
947 966 # first winter period after the commencement of this Act shall
948 967 # commence at OOhOO on Monday 21 March 1994 and shall end at 02h00 on
949 968 # Sunday 4 September 1994.
950 969

953 976 # While the entire country changes its time, Katima Mulilo and other
954 977 # settlements in Caprivi unofficially will not because the sun there
955 978 # rises and sets earlier compared to other regions. Chief of
956 979 # Forecasting Riaan van Zyl explained that the far eastern parts of
957 980 # the country are close to 40 minutes earlier in sunrise than the rest
958 981 # of the country.
959 982 #
960 983 # From Paul Eggert (2017-02-22):

963 986 # In the meantime people there can use Africa/Gaborone.
