Originally, time zones were aligned such that the Prime Meridian (longitude 0°) was the center of its own time zone, with the mean solar time there (Greenwich Mean Time or GMT) defining its local time.
Time zones were first proposed for the entire world by Canada's Sir Sandford Fleming in 1876 as an appendage to the single 24-hour clock he proposed for the entire world (located at the center of the Earth and not linked to any surface meridian!).
The number of time zones is not an absolute fact, however, since some micronations may use offsets that are not recognized by all authorities.

On March 19, 1918, the U.S. Congress established several time zones (which had been in use by railroads and most cities since 1883) and made DST official, effective March 31, for the remainder of World War I. It was observed for seven months in 1918 and 1919.
Taiwan, Republic of China implemented DST from 1945 to 1961, revoked DST from 1962 to 1973, reinstated DST from 1974 to 1975, and revoked DST from 1976 onwards.
The U.S. federal Uniform Time Act became law on April 13, 1966 and it mandated that DST begin nationwide on the last Sunday in April and end on the last Sunday in October, effective in 1967.
