Daylight Savings Time Warnings, Reminders

Time to spring into action: Daylight saving time is upon us.

Maybe it'll be a bit harder to drag yourself out of bed Sunday after losing an hour's sleep Saturday night.

But there'll be an extra hour of sunlight in the evening in the months ahead to play ball, take a walk and enjoy the outdoors.

The time change officially started Sunday at 2 a.m. local time.

It's also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios - and again, when standard time returns Nov. 6.

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

Daylight Saving became an official American standard in 1966, and was created to conserve energy. Most of Asia, Africa and South America do not observe Daylight Saving.
