BOSTON (CBS) – Don’t forget to fall back before you go to bed Saturday night.

Your clocks need go back an hour at 2 a.m. Sunday as standard time returns.

That means an extra hour of sleep and an earlier sunrise.

But it will be dark an hour earlier in the evening.

The state fire marshal says you should also take the time this weekend to change the batteries in your smoke detectors and carbon monoxide alarms.

Daylight time will be back in March.
