Shanks and Rique Pottenger, The International Atlas (6th edition), 13# San Diego: ACS Publications, Inc. (2003). 14# Unfortunately this book contains many errors and cites no sources. 15# 16# Gwillim Law writes that a good source 17# for recent time zone data is the International Air Transport 18# Association's Standard Schedules Information Manual (IATA SSIM), 19# published semiannually. Law sent in several helpful summaries 20# of the IATA's data after 1990. Except where otherwise noted, 21# IATA SSIM is the source for entries after 1990. 22# 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# For data circa 1899, a common source is: 28# Milne J.
