Daylight Saving Time ends today (10/31), and people in most parts of the country will set their clocks back an hour. The Iowa Department of Public Safety says when changing clocks, it’s also a good time to do some routine safety checks. They encourage people to check and replace batteries in smoke detectors and carbon monoxide alarms. They say it’s also a good time to make or update home disaster kits. Those should include water, food, flashlights and batteries.
