How were time zones created?

Answer 1

Scottish-Canadian Sir Sandford Fleming, chief engineer of the Canadian Pacific Railway, is widely regarded as the inventor of modern world time zones. He took the U.S. railroad system of timing zones for the railroad and expanded the idea to encompass the planet, divided into 15 degrees of longitude, for all legal, commercial and social purposes.

He began working on the project in 1876 after missing a train due to a time issue, and by 1929 all countries had accepted his proposal.

Answer 2

Local "sun time" was used until the development of the railroads, when speed of travel made this impractical and confusing. U.S. railroads needed a simplified plan to coordinate schedules of arrivals and departures. On November 18, 1883, with the cooperation of the U.S. Naval Observatory, which is the official timekeeper of the United States, four standard time zones were established in the U.S. A year later, an international conference agreed to institute a similar set of time zones for the rest of the world.

Answer 3

Because the sun is over different places at different times. The reason time zone lines are curved and all over the place is because of population zones. if Im in Pittsburgh want to go to Cleveland than there isn't much time difference.

Answer 4

Time zones were established at an international conference in 1884 held in Washington D.C., where it was agreed to divide the world into 24 time zones, each one spanning 15 degrees of longitude. This system was put in place to standardize timekeeping and simplify global communication and transportation schedules.

Answer 5

By the railroads.

See the link for information on how the time zones were established.

Answer 6

somewhere in the 1800's
