Purpose: Synchonize local time to a public time server.

This is just the basics to get started.
Examples are run on Red Hat 7.0 (Linux 2.2) and Win98SE.

Synchronize a Linux PC to a Public Time Server
----------------------------------------------

Go here: http://www.ntp.org

Get this: ntp-4.0.99k23.tar.gz (file size 1.9M)

Do this:

        tar -zxvf ntp-4.0.99k23.tar.gz

        cd ntp-4.0.99k23

        ./configure

        make    (Warnings are expected, but not a problem.)

        make install

Check the local time: date

Sync with server "tock.usno.navy.mil":
ntpdate 192.5.41.41

The output of ntpdate should like like this:

        26 Jun 18:20:51 ntpdate[16558]: adjust time server 192.5.41.41
        offset -0.016501 sec

If the command does not work, do this:

        whereis ntpdate

        ntpdate: /usr/local/bin/ntpdate

        /usr/local/bin/ntpdate 192.5.41.41
