Brookstone TimeSmart self-setting atomic clocks are programmed to set and reset themselves with very little effort from you. After a brief set-up process, your Brookstone TimeSmart will keep accurate time and can be set to automatically correct for Daylight Savings Time. Though referred to as "atomic clocks," Brookstone TimeSmart self-setting clocks are not true atomic clocks because they do not keep time by receiving the radio-controlled atomic time signal from Fort Collins, Colorado. Instead, Brookstone TimeSmart clocks utilise a battery-powered internal clock to correctly set and reset themselves after power outages or other power disruptions.
