# Category:Network Time Protocol

From ArchWiki

The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. The following are implementations of such protocol:

- Network Time Protocol daemon — The reference implementation of the protocol, especially recommended to be used on time servers. It can also adjust the interrupt frequency and the number of ticks per second to decrease system clock drift, and will cause the hardware clock to be re-synchronised every 11 minutes.

- sntp — An SNTP client that comes with NTPd. It supersedes ntpdate and is recommended in non-server environments.

- systemd-timesyncd — A simple SNTP daemon that only implements a client side, focusing only on querying time from one remote server. It should be more than appropriate for most installations.

- OpenNTPD — Part of the OpenBSD project and implements both a client and a server.

- Chrony — A client and server that is roaming friendly and designed specifically for systems that are not online all the time.

- ntpclient — A simple command-line NTP client.
