3 Configuring Network Time
Protocol (NTP)
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. It provides client time accura-
cies within a millisecond on LANs, and up to a few tens of milliseconds on WANs relative to a primary
server synchronized to Universal Coordinated Time (UTC) (via a Global Positioning Service receiver, for
example).
