ill try
if you want to something to run every hour  or day or week or month,
just write a little script and put it in /etc/cron.daily or
/etc/cron.hourly, etc.  the script can be anything, say if you want to
set your system time via ntp every day, just do this

echo "ntpdate -b -s some.ntp.server" > /etc/cron.daily/settime.cron
chmod 700 /etc/cron.daily/settime.cron

now, if you want to do things every minute or every 12 minutes or every
3rd monday or something like that, you will use the crontab file
/etc/crontab

the syntax for crontab entries are like
* * * * *  /path/to/script/to/run

where the *'s represent

minute of hour

hour of day

day of month

month

day of week

or i think thats how it goes

so if you want to run a script every 10 minutes, you could do something
like
 *  */10 * * *   root /home/dog/myscript.sh
