standard time zone

California and Washington are fully within PT. Within each zone, all clocks were synchronized. As can be seen, although there is a general standard throughout the world for defining time zones, it is still highly dependent on the country, and is subject to change. On November 18, 1883, America’s railroads began using a standard time system involving four time zones, Eastern, Central, Mountain and Pacific. As a general rule of thumb, a change of 15° of longitude should result in a time difference of 1 hour.

UTC is not dependent on daylight saving time (DST), though some countries switch between time zones during their DST period, such as the United Kingdom using British Summer Time in the summer months. All of these time zones have standard time zones that are offset from UTC from UTC-04:00 through UTC+10:00, though some additionally observe daylight saving time (DST).

Eleven are shared with either the Mountain Time Zones or the Eastern Time zones. UTC, which is based on highly precise atomic clocks and the Earth's rotation, is the new standard of today.

National Oceanic and Atmospheric Administration The 24-hour clock (Z-time) begins at midnight (00Z) at this prime meridian. Moving west across the International Date Line one moves from the -12 UTC time zone to the +12 UTC time zone.

Moving east across the International Date Line means subtracting 24 hours from the clock thereby reversing one day on the calendar. On the first Sunday in November areas on Daylight Saving Time return to Standard Time at 2:00 a.m. It wasn't until 1929 before most countries adopted hourly time zones Nepal, the final holdout, did not adopt a standard offset of UTC until 1956, and even then, has a less common offset of UTC+5:45. Eastern Time Zone (ET): UTC-05:00 – includes 22 states in the eastern part of the contiguous United States, including some parts of Canada, Mexico, Panama, and the Caribbean islands. Three states are split between the Pacific Time Zone and the Mountain Time Zone, and Alaska is split between the Pacific Time Zone and Alaska Time Zone.

Time zones throughout the world vary, and used to vary even more than they currently do.

Only 9 states are fully within the Central Time Zone. Also, charts and maps were made with reference to the observatory as the "zero" or prime meridian. For example, 00Z in the Central STANDARD Time is at 6:00 p.m. but 00Z occurs at 7:00 p.m. in Central DAYLIGHT SAVING Time. LESOTHO I N D I A AFGHANISTAN SWEDEN (AUSTL.)

Central Time Zone (CT): UTC-06:00 – includes parts of Canada, the U.S., Mexico, Central America, some of the Caribbean islands, and parts of the Eastern Pacific Ocean.

From east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
