The Network Time Protocol (NTP) is used to synchronize a computer's
time with another reference time source. This package includes ntpd
(a daemon which continuously adjusts system time) and utilities used
to query and configure the ntpd daemon.
Perl scripts ntp-wait and ntptrace are in the ntp-perl package,
ntpdate is in the ntpdate package and sntp is in the sntp package.
The documentation is in the ntp-doc package.
