Shanks and Rique Pottenger, The International Atlas (6th edition), 13 # San Diego: ACS Publications, Inc. (2003). 14 # 15 # Gwillim Law writes that a good source 16 # for recent time zone data is the International Air Transport 17 # Association's Standard Schedules Information Manual (IATA SSIM), 18 # published semiannually. Law sent in several helpful summaries 19 # of the IATA's data after 1990. 20 # 21 # Except where otherwise noted, Shanks & Pottenger is the source for 22 # entries through 1990, and IATA SSIM is the source for entries afterwards. 23 # 24 # Another source occasionally used is Edward W.
