Time Marches On, With A Little Bit More Skip This Weekend

WASHINGTON (AP/KDKA) - Time marches on, with a bit more skip this weekend.

Daylight saving time officially re-emerges at 2 a.m. local time Sunday for most of the United States, so it's best to advance your clocks by 60 minutes before bed.

You'll lose an hour's sleep Saturday night, but gain more evening light in the months ahead, when the weather warms and you want to be outdoors.

No time change is observed in Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.

Standard time returns on Nov. 5.

The Pittsburgh Public Safety Department posted a reminder to also check smoke and carbon monoxide detectors when you change your clocks.

The Commerce Department's National Institute of Standards and Technology says daylight saving time covers 238 days, or about 65 percent of the year.
