What time is it? http://time.gov/ Daylight savings time 2012 is here. Spring forward one hour. Software can adjust computer clocks automatically.
Daylight saving time [DST] or the advancing of clocks so that evenings have more daylight and mornings have less, was first implemented during World War I.
While daylight saving time is considered to be correct, daylight savings time is used more often. Asia does not observe DST.
The artificial manipulation of time in the Western world has little effect. Changing clocks twice a year is economically and socially disruptive, cancelling out any benefit.
