The Network Time Protocol Distribution
The Network Time Protocol NTP is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem.
It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time UTC via a Global Positioning Service GPS receiver, for example.
Typical NTP configurations utilize multiple redundant servers and diverse network paths, in order to achieve high accuracy and reliability.
Some configurations include cryptographic authentication to prevent accidental or malicious protocol attacks.
