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.
