Description: The ntpdate client for setting system time from NTP servers.
The ntpdate client allows a system's clock to be set to match the time
obtained by communicating with one or more servers running the NTP protocol.
.
The use of ntpdate is optional if you're running the ntp package, it can help
a system obtain lock if it starts with a time that's pretty close by using
ntpdate before starting the daemon.
.
The ntpdate client by itself is useful for occasionally setting the time on
machines that are not on the net full-time, such as laptops.
