Daylight Saving Time is starting for most of the country this weekend. Clocks will set forward an hour beginning at 2:00 a.m. Sunday, shifting an hour of daylight to the evening hours until the time moves back an hour again this fall. Fire officials say the twice-annual clock shift is a good time to test smoke and carbon monoxide detectors and change batteries if needed. The latest poll on DST finds that half of Americans don’t want to change their clocks anymore.
