Time to turn back your clocks

WASHINGTON (AP) - Leaves swirl. Autumn's chill is in the air. It must be time to set the clock back.

The official change to standard time occurs at 2 a.m. Sunday, though most folks will change their clocks Saturday night.

Some states and territories don't observe daylight-saving time and thus won't have to worry about changing their clocks back. Those are Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.

Emergency workers also remind you to change the batteries in your smoke detectors after you change the time on your clocks. They say it's something you should do twice a year.

Daylight saving time returns next March 13.
