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.
