Atomic ClocksThese clocks receive a radio signal from the the Cesium Atomic Clock at the National Institute of Standards to keep your clock accurate within one second over one million years! Note: Just like an AM radio, these clocks work perfectly at home and in a wood frame office. But don't use it in a steel frame building -- it'll be a little fuzzy!
