Introduction. Network Time Protocol (NTP) is a protocol used in order to synchronize the clocks of different network entities. It uses UDP/123. The main objective to use this protocol is to avoid the effects of variable latency over the data networks.

A time server allows you to keep your computers’ clocks synchronized with each other and with an external time server that is ultimately tied to an ideal time source. Look at the popular Network Time.
