As you may have heard, the atomic wall clock is one of the latest technological advancements in time measurement. These clocks can measure time in milli-seconds and are self-correcting. They are sometimes referred to as radio controlled clocks.

An atomic clock wall model has an internal mechanism that takes advantage of radio frequencies to synchronize its current time and date with the U.S. Atomic Clock. What is the U.S. Atomic Clock you might ask? Well, it is a radio controlled clock operated and maintained by the National Institute of Standards and Technology in Ft. Collins, Colorado.

The atomic wall clock has a small antenna incorporated into it that receives a radio signal from Ft. Collins, Colorado. This signal relays the time and date, to the millisecond, to your atomic clock. So, once your clock has been initially set to the time zone at your location, your radio controlled clock will be automatically updated from the U.S. Atomic Clock. What is even more amazing is that your clock will even adjust itself automatically for daylight savings time (DST).
