The Network Time Protocol is used to synchronize the time of a computer to a reference time source, such as a satellite receiver, atomic clock or another computer. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC).
