This is a good point. Particularly since LMT is only "correct" for very narrow regions within any given timezone.
In general LMT is not even correct for the city at the given location. Prior to 1834 the Nautical Almanac tabulated Greenwich Apparent Time, not Greenwich Mean Time. In the US insurers during the 19th century wrote policies which specified the expiration at noon on a particular date because it was reasonably likely that witnesses could testify as to whether the fire started while the sun was on the east side of buildings or the west side of buildings. For the purposes of the insurance legal time was local apparent solar time, not local mean solar time. -- Steve Allen <sla@ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB 260 Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 https://www.ucolick.org/~sla/ Hgt +250 m
