Atomic Time Standard

Provided by the U.S. National Institute of Standards and Technology, Time and Frequency Division, Boulder, Colorado, atomic time is measured through vibrations of atoms in a metal isotope that resembles mercury. The result is extremely accurate time that can be measured on instruments. Radio waves transmit this exact time throughout North America and some 'atomic' watches can receive them and correct to the exact time. To synchronize your watch with atomic standard time, call (303) 499-7111.
