For more, please see 9# the file CONTRIBUTING in the tz distribution. 10 11# From Paul Eggert (2018-05-27): 12# 13# Unless otherwise specified, the source for data through 1990 is: 14# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), 15# San Diego: ACS Publications, Inc. (2003). 16# Unfortunately this book contains many errors and cites no sources. 17# 18# Many years ago Gwillim Law wrote that a good source 19# for time zone data was the International Air Transport 20# Association's Standard Schedules Information Manual (IATA SSIM), 21# published semiannually. Law sent in several helpful summaries 22# of the IATA's data after 1990. Except where otherwise noted, 23# IATA SSIM is the source for entries after 1990. 24# 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. 28# 29# For data circa 1899, a common source is: 30# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94. 31# https://www.jstor.org/stable/1774359 32# 33# A reliable and entertaining source about time zones is 34# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). 35# 36# European-style abbreviations are commonly used along the Mediterranean. 37# For sub-Saharan Africa abbreviations were less standardized. 38# Previous editions of this database used WAT, CAT, SAT, and EAT 39# for UT +00 through +03, respectively, 40# but in 1997 Mark R V Murray reported that 41# 'SAST' is the official abbreviation for +02 in the country of South Africa, 42# 'CAT' is commonly used for +02 in countries north of South Africa, and 43# 'WAT' is probably the best name for +01, as the common phrase for 44# the area that includes Nigeria is "West Africa". 45# 46# To summarize, the following abbreviations seemed to have some currency: 47# +00 GMT Greenwich Mean Time 48# +02 CAT Central Africa Time 49# +02 SAST South Africa Standard Time 50# and Murray suggested the following abbreviation: 51# +01 WAT West Africa Time 52# Murray's suggestion seems to have caught on in news reports and the like. 53# I vaguely recall 'WAT' also being used for -01 in the past but 54# cannot now come up with solid citations. 55# 56# I invented the following abbreviations in the 1990s: 57# +02 WAST West Africa Summer Time 58# +03 CAST Central Africa Summer Time 59# +03 SAST South Africa Summer Time 60# +03 EAT East Africa Time 61# 'EAT' seems to have caught on and is in current timestamps, and though 62# the other abbreviations are rarer and are only in past timestamps, 63# they are paired with better-attested non-DST abbreviations. 64# Corrections are welcome. 65 66# Algeria 67# Rule NAME FROM TO -
