5   Network Time Protocol
Commands
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 millisecond on WANs. Typical NTP configura-
tions utilize multiple redundant servers and diverse network paths in order to achieve high accuracy and 
reliability. 
It is important for networks to maintain accurate time synchronization between network nodes. The stan-
dard timescale used by most nations of the world is based on a combination of Universal Coordinated 
Time (UTC) (representing the Earth’s rotation about its axis) and the Gregorian Calendar (representing the 
Earth’s rotation about the Sun). UTC time is disseminated by various means, including radio and satellite 
navigation systems, telephone modems, and portable clocks.
The MIB information for NTP is as follows:
