| + | ====== 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 | ||
