Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over Ethernet.

CueServer uses NTP to keep its clock as accurate as possible without requiring the user to adjust the time manually.

NTP is intended to synchronize computers to within a few milliseconds of Coordinated Universal Time (UTC). It an algorithm to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions. Asymmetric routes and network congestion can cause errors of 100 ms or more.

Because a CueServer that intends to use NTP to synchronize its time must be able to reach a NTP Server via Ethernet, this function can only work if the CueServer is on a network that has access to the Internet, or the facility must have an NTP Server on its local network.
