1025 # From Paul Eggert (2006-03-22):
1026 # A good source for time zone historical data outside the U.S. is
1027 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
1028 # San Diego: ACS Publications, Inc. (2003).
1029 #
1030 # Gwillim Law writes that a good source
1031 # for recent time zone data is the International Air Transport
1032 # Association's Standard Schedules Information Manual (IATA SSIM),
1033 # published semiannually.  Law sent in several helpful summaries
1034 # of the IATA's data after 1990.
1035 #
1036 # Except where otherwise noted, Shanks & Pottenger is the source for
1037 # entries through 1990, and IATA SSIM is the source for entries afterwards.
1038 #
1039 # Other sources occasionally used include:

1041 #       Edward W. Whitman, World Time Differences,
1042 #       Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated),
1043 #       which I found in the UCLA library.
