ALSO CALLED:
Network Time Protocol
DEFINITION: Network Time Protocol (NTP) is a protocol that is used to synchronize computer clock times in a network of computers. Developed by David Mills at the University of Delaware, NTP is now an Internet standard. In common with similar protocols, NTP uses Coordinated Universal Time (UTC) to synchronize computer clock times to a millisecond, and sometimes to a fraction of a millisecond.Accurate time

A Hidden Security Danger: Network Timing
sponsored by Symmetricom
WHITE PAPER:
Most anyone who uses a PC no doubt sees the little clock at the bottom of the screen,dutifully ticking off the minutes of the passing day. But chances are they don’t often think about the role that clock plays in the network to which the PC is attached.

NTP DEFINITION (continued): … across a network is important for many reasons; even small fractions of a second can cause problems. For example, distributed procedures depend on coordinated times to ensure that proper sequences are followed. Security mechanisms depend on coordinated times across the network. File system updates carried out by a number of computers also depend on synchronized clock times. Air traffic control systems provide a graphic illustration of the need for coordinated times, since flight paths require very precise timing (imagine the situation if air traffic controller computer clock times were not synchronized).UTC … NTP definition sponsored by SearchNetworking.com, powered by WhatIs.com an online computer dictionary
