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:

The most important factor in providing accurate, reliable time is 

the selection of NTP servers to be used in the configuration file. 

Typical NTP configurations utilize multiple redundant servers and 

diverse network paths in order to achieve high accuracy and re-

liability. Our NTP configuration supports two existing public NTP 

synchronization subnets.
