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 meanest life, the poorest existence, is attributed to God’s will, but as human beings become more affluent, as their living standard and style begin to ascend the material scale, God descends the scale of responsibility at a commensurate speed.”
—Maya Angelou (b. 1928)
“You all talk like somebody else made these laws and Pharaoh don’t know nothing about ‘em. He makes ‘em his own self and he’s glad when we come tell him they hurt. why, that’s a whole lot of pleasure to him, to be making up laws all the time and to have a crowd like us around handy to pass all his mean ones on. Why, that’s a whole everything under the sun! Next thing you know he’ll be saying cats can’t have kittens.”
—Zora Neale Hurston (1891–1960)
