[ Watch The Video: NIST-F2 Atomic Clock Sets The Time Standard ] NIST The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has officially launched a new atomic clock, called NIST-F2, to serve as a new US civilian time and frequency standard, along with the current NIST-F1 standard. NIST-F2 would neither gain nor lose one second in about 300 million years, making it about three times as accurate as NIST-F1, which has served as the standard...

The world's best caesium atomic clocks control Coordinated Universal Time (UTC), an atomic time scale on which the time zones used in everyday life are based. But also in navigation (GPS), astronomy, telecommunications, geodesy and physical fundamental research, accurate timing is of essential importance. Until recently, three of PTB's clocks belonged to the exclusive club of primary caesium atomic clocks. Now a fourth one, the caesium fountain clock CSF2, has joined in. This month, its data...
