NIST-F2 Atomic Clock Sets The Time Standard

A new atomic clock based on a “fountain” of cesium atoms, to serve as the next U.S. civilian time standard. NIST-F2 would neither gain nor lose one second in 300 million years, making it more than twice as accurate as its predecessor, NIST-F1, the U.S. civilian time and frequency standard since 1999.
