comment = "Network Time Protocol (NTP) daemon"

desc = <<EOD
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.
