Time Zone

A time zone is a region on Earth that has a uniform standard time for legal, commercial, and social purposes. It is convenient for areas in close commercial or other communication to keep the same time, so time zones tend to follow the boundaries of countries and their subdivisions.

Most of the 40 time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few are offset by 30 or 45 minutes. Some higher latitude countries use daylight saving time for part of the year, typically by changing clocks by an hour. Many land time zones are skewed toward the west of the corresponding nautical time zones. This also creates a permanent daylight saving time effect.

Famous quotes containing the words zone and/or time:

    He who, from zone to zone,
    Guides through the boundless sky thy certain flight,
    In the long way that I must tread alone,
    Will lead my steps aright.
    William Cullen Bryant (1794–1878)

    Many’s the time I’ve seen Barney go off, just that same way. Goodbye. Sometimes he’d wave. Ten to one he wasn’t even seein’ me. He was thinkin’ about all those men, you see. All those men who went out to fight, to kill, be killed. And blast his eyes, lovin’ it.
    Lamar Trotti (1898–1952)
