Firefighters are encouraging everyone to switch their smoke detector batteries when they change their clocks.
Firefighters say if you can put both tasks together every time we spring forward or fall backward it will really make a big difference.
A captain with the Reno Fire Department says authorities often respond to fires that could have been prevented with smoke detectors.
"It's a problem everywhere and mostly because people don't change their batteries," said Captain David Sundae. "And the battery starts chirping and people don't want to change the batteries so they just get rid of the smoke detector."
The Reno Fire Department recommends that you have one smoke detector in each bedroom and one on each level of your home including the basement.
Standard time officially resumes at 2am, Sunday morning.
