This section describes the definition and objective of NTP.
The Network Time Protocol (NTP) is an application layer protocol used for clock synchronization between the distributed time server and client on the Internet. The clock of any local system that runs NTP can be synchronized by other clock sources, and the system can also function as a clock source to synchronize the clock of other systems. In addition, two devices can exchange NTP packets for mutual synchronization.
NTP is to synchronize the time of all devices that have a clock, ensuring time consistency on the entire network and allowing devices to provide various applications based on the unified time.
