Network Time Protocol

The NTP Project conducts Research and Development in NTP, a protocol designed to synchronize the clocks of computers over a network to a common timebase. NTP is what ensures the reliability of billions of devices around the world, under the sea, and even in space. The NTP Project produces an open source Reference Implementation of the NTP standard, maintains the implementation documentation, and develops the protocol and algorithmic standard that is used to communicate time between systems.
