-Network Time Protocol server and client
+The Network Time Protocol (NTP, RFC 5905) allows a system to set its time-of-day
+clock automatically by contacting a remote system known to have accurate time.
+NTP servers are typically organised in a hierarchy in which the highest-level
+servers receive time from a reliable external timekeeping device (such as an
+atomic clock or a GPS receiver), and each subordinate server in the hierarchy
+knows its distance from the timekeeping device it is ultimately synchronised to.
+
+Unlike earlier protocols such as the Time Protocol (RFC 868), NTP can provide
+very accurate (sub-millisecond) time synchronisation even over high-latency
+networks.  Many NTP servers are accessible over the public Internet, most of
+which participate in the NTP Pool system.
+
+This package provides the ntpd(8) daemon which implements both the client
+and server part of NTP depending on its configuration, and the ntpdate(8)
+utility which can be used for testing or one-off time synchronisation.
+
+A periodic(8) script to monitor the status of the NTP daemon is also provided.
