An atomic clock has an atomic oscillator inside (such as a cesium or rubidium oscillator). Some manufacturers refer to their radio controlled clocks as "atomic clocks", which isn't really true. This page provides information about radio controlled clocks, including how they work, where they work, and what to do when they don't work. During the transition from standard time to daylight saving time (DST) they "spring forward" one hour, and when DST is finished they "fall back" one hour.ĭue to technology advances and the economies of scale, radio controlled clocks are now very inexpensive, often costing just a few dollars more than conventional clocks. This means that you should never have to adjust them. They have a tremendous advantage over conventional clocks, they are always right! When working properly, radio controlled clocks always display the correct time, down to the exact second. These clocks are sold in all forms: as wall clocks, desk clocks, travel alarms, and wristwatches. How They Workīy now, you have probably seen or own a radio controlled clock.
