 +====== Setting the Clock Using rdate ======
  
 +First, you'll need rdate installed. ​ Note that rdate uses an older time protocol that is not supported by all NIST servers, but is supported by most.
 +
 +Just add a cronjob that runs rdate once a day.  You can modify this to run every hour as well.
 +
 +Before you start, find out where rdate is located by running:
 +
 +  which rdate
 +
 +It's typically installed in /usr/bin or /​usr/​sbin. ​ Modify the cron job to reflect the correct path.
 +
 +Here are all the steps.
 +
 +  * Edit the root cronjob
 +
 +  crontab -e
 +
 +  * Add the following line
 +
 +  0 6 * * *       /​usr/​sbin/​rdate -s time-c.timefreq.bldrdoc.gov
 +
 +  * Save and close
