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.

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
|
35# for +0:00 through +3:00, respectively,
36# but Mark R V Murray reports that
37# 'SAST' is the official abbreviation for +2:00 in the country of South Africa,
38# 'CAT' is commonly used for +2:00 in countries north of South Africa, and
39# 'WAT' is probably the best name for +1:00, as the common phrase for
|
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".
|
41# He has heard of "Western Sahara Time" for +0:00 but can find no reference.
|
43#
|
43# To make things confusing, 'WAT' seems to have been used for -1:00 long ago;
44# I'd guess that this was because people needed _some_ name for -1:00,
45# and at the time, far west Africa was the only major land area in -1:00.
46# This usage is now obsolete, as the last use of -1:00 on the African
47# mainland seems to have been 1976 in Western Sahara.
|
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. |

49# To summarize, the following abbreviations seem to have some currency:
50# -1:00 WAT West Africa Time (no longer used)
51# 0:00 GMT Greenwich Mean Time
52# 2:00 CAT Central Africa Time
53# 2:00 SAST South Africa Standard Time
54# and Murray suggests the following abbreviation:
55# 1:00 WAT West Africa Time
56# I realize that this leads to 'WAT' being used for both -1:00 and 1:00
57# for times before 1976, but this is the best I can think of
58# until we get more information.
