For instance, the current U.S. civilian time standard is NIST-F1 -- a cesium fountain clock -- which must be averaged for about 400,000 seconds (about five days) to achieve its best performance. On the other hand, the new ytterbium clocks achieve that same result in about one second of averaging time. |
