If you distribute software or equipment that uses NTP, please see our ...NTP is a protocol that is designed to time-synchronize a network of machines. NTP is documented in RFC 1305 and runs over UDP. An NTP network usually gets its time from an authoritative time source, such as a radio clock or an atomic clock attached to a time server. NTP then distributes this time across the network.

In the Classic Windows Control Panel there is also link called “Date and Time.”. Click on “Set the time and date” or “Date and Time” depending on your Windows environment.

Click ...This memo specifies Network Time Security (NTS), a mechanism for using Transport Layer Security (TLS) and Authenticated Encryption with Associated Data (AEAD) to provide cryptographic security for the client-server mode of the Network Time Protocol (NTP). NTS is structured as a suite of two loosely coupled sub-protocols.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.

The NTP protocol makes use of the UDP transport layer protocol on port 123 to communicate with the different NTP servers around the world.A very important detail is that this NTP protocol makes use of UDP port 123 both in the source port and in the destination port, so we must take it into account if we have devices behind a firewall or if …server 2.north-america.pool.ntp.org. server 3.north-america.pool.ntp.org.
