Question

3. is the time officially adopted by a country.​

Answer 1

Answer:

On November 18, 1883, America's railroads began using a standard time system involving four time zones, Eastern, Central, Mountain and Pacific. Within each zone, all clocks were synchronized.

This was the dream articulated by Scottish-Canadian engineer Sandford Fleming and officially adopted by diplomats at the 1884 Prime Meridian Conference in Washington, D.C.: a world divided into 24 zones, each with a single mean time determined by astronomers at the Royal Observatory in Greenwich.

New Zealand

First Countries to Use Time Zones

New Zealand (then a British colony) adopted a standard time zone that became known as the New Zealand Mean Time in November 1868, making the country the first one to adopt a standardized time zone observed in the entire colony.

The United States is divided into six time zones: Hawaii-Aleutian time, Alaska time, Pacific time, Mountain time, Central time and Eastern time.
