Radio-controlled (or "atomic") clocks and weather stations set themselves automatically by tapping into the time signal broadcast from the cesium fountain atomic clock located in Boulder, Colorado. Accurate to 1 second every 60 million years, the atomic clock signal is broadcast over North America by the National Institute of Standards and Technology. Television and radio stations, financial institutions, even NASA use this frequency for precise timekeeping! Radio-controlled clocks may have difficulty finding the NIST signal in Alaska, Hawaii, Maine and parts of Canada. Requires 1 AA battery.
