Another town might decide that sunrise is at 7:30 a.m. THE HISTORY OF TIME ZONESīefore the days of trains and airplanes, most communities set their clocks to whatever made sense for their location. People living on the East Coast of the United States will see the sun rise before people living on the West Coast. However, this doesn’t happen at the same time in every location. The rotation of the earth makes it appear that the sun rises in the east, moves across the sky and sets in the west. Understanding time zones and how they work is important, especially if you don’t want to miss the start of the big game or other live events. TeyTey123452 wrote: " "MOM!

Today, the Uniform Time Act of 1966 (15 U.S.C. This responsibility was transferred from the Interstate Commerce Commission to DOT when Congress created DOT in 1966. Local decisions on which time zone to adopt were usually influenced by the time used by the railroads.įederal oversight of time zones began in 1918 with the enactment of the Standard Time Act, which vested the Interstate Commerce Commission with the responsibility for establishing boundaries between the standard time zones in the continental United States. States and municipalities then adopted one of the four zones, which were the eastern, central, mountain, and Pacific Time zones. and Canadian railroads adopted a four-zone system to govern their operations and reduce the confusion resulting from some 100 conflicting locally established “sun times” observed in terminals across the country.
