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 accuracies
|
|
typically within a millisecond on LANs and up to a few tens of
|
|
milliseconds on WANs relative 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 and some provide automatic
|
|
server discovery using IP multicast.
