Are you an hour late for something today? Did you set change your alarm clock?
Daylight Saving Time for 2013 began Sunday.
By setting our clocks ahead one hour at 2 a.m., we left Standard Time.
Twice a year, most localities change their clocks—ahead on the second Sunday in March and back on the first Sunday in November.
The change, ostensibly, is to save energy by taking advantage of the longer daylight hours during the warmer months.
