CHICAGO (CBS) — Daylight saving time ends on Sunday, meaning you’ll need to turn your clocks back tonight.

Standard time resumes at 2 a.m. Sunday, though most people find it’s easier to “fall back” and set their clocks back an hour before they go to bed to get an extra hour of sleep.

While you’re at it, the Chicago Fire Department wants you to change the battery in your smoke detector.

Chief Joe Roccasalva says they’ve been making that pitch – change your clocks, change your batteries – for about 20 years.

Even so, Roccasalva said too many people forget to check their smoke detector.

“We still see it all the time. If you look at our statistics ninety percent of our fire deaths don’t have a working smoke detector,” Roccasalva said. “And is it most of the time that it does exist but the battery is not there. Correct.”

Daylight saving time returns in March.
