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:
“Where shall we look for standard English but to the words of a standard man?”
—Henry David Thoreau (1817–1862)
“Fair Hope! our earlier Heaven! by thee
Young Time is taster to Eternity.
The generous wine with age grows strong, not sour,
Nor need we kill thy fruit to smell thy flower.
Thy golden head never hangs down
Till in the lap of Love’s full noon
It falls and dies: Oh no, it melts away
As doth the dawn into the day,
As lumps of sugar lose themselves, and twine
Their subtle essence with the soul of wine.”
—Abraham Cowley (1618–1667)
