Fall Back! Daylight Saving Time Has Ended

SAN FRANCISCO (CBS SF) -- Don't forget to set your clocks back an hour -- Daylight Saving Time ended Sunday at 2 a.m.

The good news: most Americans gained an extra hour.

Hawaii and Arizona don't have Daylight Saving Time. More states may join them.

This year, 12 states had bills proposed to abandon the decades-old practice, including California.

The Red Cross advises people to use the occasion to change the batteries in their smoke alarms.
