The American Atlas, Expanded 5th Edition

Contains data for over 150,000 locations, with time zones from 1850 to 2000, and the complete clock setting history of every city in the U.S. large enough to have a post office. This supercedes all previous sources and has easy to follow tables, which makes The American Atlas, 5th Edition, the most comprehensive reference for daylight savings time, war time, latitudes, and longitudes.
