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 TYPE IN ON AT SAVE LETTER/S 68Rule Algeria 1916 only - Jun 14 23:00s 1:00 S 69Rule Algeria 1916 1919 - Oct Sun>=1 23:00s 0 - 70Rule Algeria 1917 only - Mar 24 23:00s 1:00 S 71Rule Algeria 1918 only - Mar 9 23:00s 1:00 S 72Rule Algeria 1919 only - Mar 1 23:00s 1:00 S 73Rule Algeria 1920 only - Feb 14 23:00s 1:00 S 74Rule Algeria 1920 only - Oct 23 23:00s 0 - 75Rule Algeria 1921 only - Mar 14 23:00s 1:00 S 76Rule Algeria 1921 only - Jun 21 23:00s 0 - 77Rule Algeria 1939 only - Sep 11 23:00s 1:00 S 78Rule Algeria 1939 only - Nov 19 1:00 0 - 79Rule Algeria 1944 1945 - Apr Mon>=1 2:00 1:00 S 80Rule Algeria 1944 only - Oct 8 2:00 0 - 81Rule Algeria 1945 only - Sep 16 1:00 0 - 82Rule Algeria 1971 only - Apr 25 23:00s 1:00 S 83Rule Algeria 1971 only - Sep 26 23:00s 0 - 84Rule Algeria 1977 only - May 6 0:00 1:00 S 85Rule Algeria 1977 only - Oct 21 0:00 0 - 86Rule Algeria 1978 only - Mar 24 1:00 1:00 S 87Rule Algeria 1978 only - Sep 22 3:00 0 - 88Rule Algeria 1980 only - Apr 25 0:00 1:00 S 89Rule Algeria 1980 only - Oct 31 2:00 0 - 90# Shanks & Pottenger give 0:09:20 for Paris Mean Time;

This year it will be observed September 13 (September is quite 232# hot in Egypt), and the idea is to make fasting easier for workers by 233# shifting business hours one hour out of daytime heat.
