Easy to find with google, look at /etc/crontab or.... well... this is too easy to find.

0 * * * * /usr/sbin/ntpdate -s 0.asia.pool.ntp.org

Change the path to ntpdate as neede on your system.
The "-s" commandline option is used to log to syslog intead of to default output (mostly screen).

You'd better not do that. You should consider using of ntpd (it's daemon to sync time).

Just out of curiousity... Why is it better to use the daemon Zeiter?
I also use a cronjob, but I only let it run once a day.

Good answer and description can be found in man and here http://serverfault.com/questions/16467/compare-ntpd-and-ntpdate as well.
