Computers, Communications, Atomic Clocks and the NTP Server
Friday, March 19th, 2010 | Computers |
Time synchronisation on computer networks is often conducted by the NTP server. NTP time servers do not generate any timing information themselves but are merely methods of communicating with an atomic clock. The precision of an atomic clock is widely talked about.
