[ol7_latest] ntp-4.2.6p5-29.0.1.el7.x86_64

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.
