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:
“Society’s double behavioral standard for women and for men is, in fact, a more effective deterrent than economic discrimination because it is more insidious, less tangible. Economic disadvantages involve ascertainable amounts, but the very nature of societal value judgments makes them harder to define, their effects harder to relate.”
—Anne Tucker (b. 1945)
“We’re headed for collapse, if you want my opinion, Missy. I can see it in the fallin’ off of the quality of vagrants. There was a time you could find real good company in almost any jungle you’d pick, men who could talk, men who’d read a book now and then; and now, what do you find, a lot of dirty little guttersnipes no decent tramp would want to associate with.
Well, it’s been that way all through history.”
—John Dos Passos (1896–1970)
