WASHINGTON — 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.
Daylight saving time returns March 13.
