With leaves swirling and an autumn chill in the air, nature reminds us it's time for most Americans to set the clock back.
Officially, the change to standard time occurs at 2 a.m. Sunday. Most folks will set their clocks Saturday night.
Remember, it's fall back an hour. Otherwise, you'll be an hour early on Sunday for church, golf or whatever. Residents of Hawaii, most of Arizona and some U.S. territories don't have to change since they did not observe daylight saving time, which resumes the second Sunday in March.
