Daylight saving time ends at 2 a.m. this Sunday, November 3 -- which means we will set clocks back one hour.
Standard time will last until Sunday, March 9, with the return of daylight saving time.

The time change is a reminder to change the batteries on all home smoke alarms, and ensure those smoke alarms are working properly. Either way, they should be replaced every 10 years.
