What Is Atomic Time Standard? |
|
Answer» 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. The result is extremely accurate time that can be measured on instruments. A radio signal transmits this EXACT time throughout North America and some 'atomic' watches and clocks can RECEIVE them and correct to the exact time.
