What is Network Time System?
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. NTP is designed to synchronize the clocks of computers to within a few milliseconds of Coordinated Universal Time (UTC).
Here are some key points about NTP:
- It was originally designed by David L. Mills in 1985 and has been continuously updated and improved since then.
- It works by adjusting the system clock on each participating computer to match the time reported by trusted time servers.
- NTP uses a hierarchical, semi-layered system of time sources that provide accurate timing information. At the top are servers synchronized to national time scales using specialized hardware like atomic clocks or GPS receivers.
- The protocol includes measures for authentication, redundancy, and clock filtering to provide robust and accurate time corrections even over less reliable networks.
- Typical NTP deployments can maintain time to within 10-50 milliseconds on LANs and ~100 milliseconds or better over WANs relative to UTC.
- NTP is one of the oldest internet protocols still in use and remains crucial for applications like logging, timestamping, simulation, aviation systems, financial trading, and more.
