What is the atomic clock? Where is it? - Reader in St. Petersburg

The atomic clock, known as NIST-F1, is at the Department of Commerce's National Institute of Standards and Technology laboratories in Boulder, Colorado. The cesium fountain atomic clock is the nation's primary time and frequency standard. One of the most accurate clocks in the world, it would neither gain nor lose a second in more than 60-million years. It replaced the NIST-7, a cesium beam atomic clock that served as the United States' primary time and frequency standard from 1993-1999.
