NTP (Network Time Protocol) is by David L. professor Mills proposed in 1985 that in addition to estimating the round-trip latency of packets on the network, it can also independently estimate the Computer Clock Deviation, so as to achieve high precision computer calibration on the network, it is a communication protocol designed to enable different machines to maintain the same time on the Internet.

the Internet to synchronize the time of the computer is very convenient, this way in the LAN has been widely used. Microsoft has embedded the Network Time Protocol (NTP) in a Windows XP system that allows computer time calibration in a LAN or wide area network as long as the computer is networked.
