9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (3rd edition),
11# San Diego: ACS Publications, Inc. (1991).
12# Except where otherwise noted, it is the source for the data below.

14# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually. Law sent in several helpful summaries
18# of the IATA's data after 1990.
19#
20# Except where otherwise noted, Shanks is the source for entries through 1990,
21# and IATA SSIM is the source for entries after 1990.
22#
28f540f4
RM
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# A reliable and entertaining source about time zones is
28# Derek Howse, Greenwich time and the discovery of the longitude,
29# Oxford University Press (1980).
30#
31# I invented the abbreviations marked `*' in the following table;
32# the rest are from earlier versions of this file, or from other sources.

81# From Paul Eggert (1996-05-04):
82# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
83# but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
84# <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,
85# though it did use DST in 1995. We guess Yerevan stayed in sync with Moscow
86# between 1990 and 1995, but stopped using DST in 1996.

164# China is across 4 physical time zones, before Feb 1, 1986 only the

518# changes may need to be made on a semi-annual basis. One thing is entrenched

520# time annually. Ever since 1993, the change to daylight savings time is
521# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
