Maybe it'll be a bit harder to drag yourself out of bed tomorrow after losing an hour's sleep tonight. But there'll be an extra hour of sunlight in the evening in the months ahead to play ball, take a walk and enjoy the outdoors. The time change officially starts Sunday at 2 a.m., so consider setting clocks ahead by 60 minutes before retiring, tonight. It's also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios - and again, when standard time returns Nov. 6.
