Configuration Information
The following configuration file defines various NTP
stratum 2 servers with open access from different continents. It also
creates a drift file where ntpd stores the frequency
offset. Since the documentation included with the package is sparse,
visit the NTP website at
for more information.

Synchronizing the time
There are two options. Option one is to use run ntpd
continuously and allow it to synchronize the time in a gradual manner. The other
option is to run ntpd periodically (using cron)
and update the time each time ntpd is scheduled.
If you choose Option one, then install
/etc/rc.d/init.d/ntp
init script included in the
package.
make install-ntp
If you prefer to start ntpd periodically, add the following command to
the root's crontab:
ntpd -q
