Shanks and Rique Pottenger, The International Atlas (6th edition), 16# San Diego: ACS Publications, Inc. (2003). 17# Unfortunately this book contains many errors and cites no sources. 18# 19# Many years ago Gwillim Law wrote that a good source 20# for time zone data was the International Air Transport 21# Association's Standard Schedules Information Manual (IATA SSIM), 22# published semiannually. Law sent in several helpful summaries 23# of the IATA's data after 1990. Except where otherwise noted, 24# IATA SSIM is the source for entries after 1990. 25# 26# Another source occasionally used is Edward W. Whitman, World Time Differences, 27# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which 28# I found in the UCLA library. 29# 30# For data circa 1899, a common source is: 31# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94. 32# https://www.jstor.org/stable/1774359 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 in the 1990s: 55# +02 WAST West Africa Summer Time 56# +03 CAST Central Africa Summer Time 57# +03 SAST South Africa Summer Time 58# +03 EAT East Africa Time 59# 'EAT' seems to have caught on and is in current timestamps, and though 60# the other abbreviations are rarer and are only in past timestamps, 61# they are paired with better-attested non-DST abbreviations. 62# Corrections are welcome. 63 64# Algeria 65# Rule NAME FROM TO -
