It’s time to set the clocks ahead this weekend as Daylight Saving Time begins. At 2 a.m. Sunday, time will leave standard time by one hour, which will make mornings a bit darker and nightfall come a bit later. Pella Fire Chief Randy Bogaard says Daylight Saving Time changes in the spring and fall are a great time to replace batteries in smoke and carbon monoxide detectors. He says beyond the battery change, it’s also important to check the expiration date on the alarms themselves to ensure they aren’t past the manufacturers’ recommended lifespan.
