WASHINGTON (AP) - It's finally time to reclaim that hour of sleep you lost last spring.

Most of the country turned back the clocks this weekend for the annual shift back to standard time.

The majority of folks did the switch before hitting the sack Saturday night, even though the change didn't become official until 2 a.m. Sunday local time.

Residents of Hawaii, most of Arizona and some U.S. territories don't have to change since they do not observe daylight-saving time.

Public safety officials say this is also a good time to put a new battery in the smoke alarm, no matter where you live.

Daylight saving time returns the second Sunday in March.
