reference to radio and atomic clocks located on the Internet. This protocol is capable of synchronizing

distributed clocks within milliseconds over long time periods.

NTP server

Network Timing Protocol server. A server that uses NTP. NTP is a protocol built on top of TCP that

ensures accurate local time-keeping with reference to radio and atomic clocks located on the Internet.
