The Windows Time service follows the Network Time Protocol (NTP) specification, which requires the use of UDP port 123 for all time synchronization. Whenever the computer synchronizes its clock or provides time to another computer, it happens over UDP port 123. This port is reserved by the Windows Time service as the destination port.

Network Time Protocol is used to synchronize the clocks of computers on a network. How accurately it synchronizes the clocks of client computers depends on a number of factors.
