Jitter: The jitter associated with a timing reference indicates the magnitude of variance, or dispersion, of the signal. Different timing references have different amounts of jitter. The more accurate a timing reference, the lower the jitter value. Jitter is usually measure in milliseconds.

Offset: Offset generally refers to the difference in time between an external timing reference and time on a local machine. The greater the offset, the more inaccurate the timing source is. Synchronised NTP servers will generally have a low offset. Offset is generally measured in milliseconds.

Stratum: The Stratum of a NTP server denotes its level in the timing hierarchy. A stratum 1 NTP server obtains time from an external timing reference. Stratum 2 devices obtain time from stratum 1 devices and pass timing information to the next level and so on.

Delay: Delay in a NTP server describes the round-trip delay or latency of a timing message passed from client to server and back again. The delay is important so that network delays can be calculated and accounted for by a time client.

Reference Clock: A NTP reference clock is an external hardware clock that a NTP server utilises for accurate time synchronisation. GPS and radio time and frequency broadcasts are commonly used as NTP reference clocks. The NTP distribution, which is available for LINUX, provides source code to operate a large number of external reference clocks.
