* get a current ntp rpm (e.g., ntp-4.0.99k-4.i386.rpm)
    and install it
 * in /etc/ntp.conf, comment out the server entries and replace with
    local server ip addresses.  The lines (near the top) should be:
         #server 127.127.1.0     # local clock
         #fudge  127.127.1.0 stratum 10
         server 128.146.37.10
         server 128.146.38.12
 * make sure that /etc/rc.d/init.d/ntpd points to the correct function
    library (/etc/rc.d/init.d/functions instead of /etc/rc.d/functions).
    This may be distribution/version dependent.  Just check that it points
    to the correct place.
 * /etc/rc.d/init.d/ntpd restart   
 * check /var/log/messages to see if it is working
