Daylight saving time will end this weekend, when clocks "fall back" one hour to standard time, starting at 2 a.m. Sunday. That means an extra hour of sleep for many.

Maryland State Fire Marshal William Barnard is recommending that residents change the batteries in their smoke alarms and carbon monoxide detectors at the same time that they turn back their clocks. Barnard says that having working fire alarms and carbon monoxide detectors can double a family's chances of surviving a home fire or instance of unsafe carbon monoxide levels.
