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 Overview. Network Time Protocol (NTP) is an application layer protocol used for time synchronization between hosts on a TCP/IP network. Its goal is to ensure that all computers on a network agree on the system clock since even a small difference can create problems. For example, if there is more than 5 minutes difference ... The Network Time Protocol (NTP) is used by hundreds of millions of computers and devices to synchronize their clocks over the Internet. If your computer sets its own clock, it likely uses NTP.
