In many communication and production processes, time accuracy and synchronization are crucial for the functionality of the systems, for example in communication and information technology, data transmission and network technology, in process sequences in production technology, satellite technology or the synchronization of clocks. Time servers are responsible for the distribution of high-precision time signals
. Time servers can be dedicated or part of another server, they can be public or proprietary. As network components, they transmit high-precision time signals and time stamps to synchronize networks, computers
, and system components with time-accurate synchronization signals.DCF77
. Time stamps from other time servers can also be used as time reference.Network Time Protocol (NTP), the simpler version, the Simple Network Time Protocol (SNTP) or the highly precise Precision Time Protocol (PTP).
