The Network Time Protocol (NTP) is used to synchronize a computer's
time with another reference time source. The ntp package contains
utilities and daemons which will synchronize your computer's time to
Coordinated Universal Time (UTC) via the NTP protocol and NTP servers.

time), while ntp-client package contains ntpdate (a program for
retrieving the date and time from remote machines via a network).
