Standard Time

Standard time is the result of synchronizing clocks in different geographical locations within a time zone to the same time rather than using the local meridian as in local mean time or solar time. Historically, this helped in the process of weather forecasting and train travel. The concept became established in the late 19th century. The time so set has come to be defined in terms of offsets from Universal Time. Where daylight saving time is used, the term standard time typically refers to the time without the offset for daylight saving time.

The adoption of Standard Time, because of the inseparable correspondence between time and longitude, solidified the concepts of halving the globe into an eastern and western hemisphere, with one Prime Meridian (as well its opposite International Dateline) replacing the various Prime Meridians that were in use.

Famous quotes containing the words standard and/or time:

    The art of advertisement, after the American manner, has introduced into all our life such a lavish use of superlatives, that no standard of value whatever is intact.
    Wyndham Lewis (1882–1957)

    The vines of her arms
    didn’t cling to the ends of his clothes,
    or did she plant herself in the doorway,
    hurl herself at his feet,
    or utter the word “Stay!”
    But as that fool began to go
    at the time when it was dark with swarming clouds,
    the slim girl blocked her lover’s way
    with only a rising river
    made with her flood of tears.
    Amaru (c. seventh century A.D.)
