The Network Time Protocol is a protocol published in 1985 for synchronizing clocks in computer systems. The term NTP refers to both the protocol and the client-server programs that run on computers.

The NTP client requests an exchange of time with the NTP server. As a result of this exchange, the connection delay can be checked. Then the local clock is adjusted to that of the server. After synchronization, the client updates its clock every 10 minutes.

NTP servers have access to high-precision atomic clocks and GPS clocks. Since it is very expensive to equip all servers with special receivers, some computers are equipped with them. These then synchronize the times of the networked computers. NTP is based on the Coordinated Universal Time (UTC) and expects an own conversion of the user.

NTP is of great benefit to the user, as more accurate synchronization can lead to fewer errors. Thus it can be ensured that planned processes remain within the time frame. Also, when updating systems, it can be of utmost importance to keep a strict time frame.

Furthermore, network acceleration and network management systems can rely on the accuracy of timestamps.
