AMS was designated as an Engineer field activity, effective July 1, 1942, by General Order 22, OCE, June 19, 1942.
Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Aircraft operations on land now part of Wright-Patterson Air Force Base began in 1904–1905 when Wilbur and Orville Wright used an 84-acre (340,000 m 2) plot of Huffman Prairie [9] for experimental test flights with the Wright Flyer III. Their flight exhibition company and the Wright Company School of Aviation returned 1910–1916 to use the ...
Alaska had local times corresponding to between UTC+11:30 and UTC+15:10 until 1867 (24 hours were deducted in 1867 to make the date correspond to rest of United States). These times were local mean times and not time zones. UTC+14:00 was used as a daylight time before 1982 in the parts of very eastern Russia that used Kamchatka Time.

The intersection of a UTM zone and a latitude band is (normally) a 6° × 8° polygon called a grid zone, whose designation in MGRS is formed by the zone number (one or two digits – the number for zones 1 to 9 is just a single digit, according to the example in DMA TM 8358.1, Section 3-2, [1] Figure 7), followed by the latitude band letter ...
