This Sunday, we spring forward at 2 a.m., so make you set your clock an hour ahead. And, as the Fire Department always reminds us during daylight savings time, it's a great time to change the batteries in your smoke detectors. (While many homes have smoke detectors, 33% have dead batteries—a situation that could be dangerous.) Duracell has donated 9-volt batteries to the FDNY Foundation, and the FDNY and Duracell will be giving them out in all five boroughs today through Sunday. Here are the locations:
