An Acronym for Network Time Protocol.

A protocol that allows synchronising a computer's internal clock (and system time) with an external source, such as a computer with a more accurate clock. Machines that are synchronised with an atomic clock or GPS are stratum 1. Machines that synchronise to these machines are stratum 2, and so on. Normally stratum 1 machines aren't available for public connections.
