BOULDER, Colo. (April 3, 2014) The National Institute of Standards and Technology in Boulder, Colo., has a new atomic clock that isn't supposed to gain or lose a second in roughly 300 million years.
The new clock is at the institute's Boulder center.
The clock is the nation's civilian time standard.
The U.S. Naval Observatory maintains military time.
The new clock is about three times more accurate than the old one.
The institute says it will keep operating both and use comparisons to improve them.
Banks, computer networks and others use the atomic clock to synchronize their own.
The institute's radio broadcasts update about 50 million timekeepers daily and its Internet service gets about 8 billion automated synchronization requests daily.
