[CentOS] Cron job? or something else? help..

Hello,

i have a certain issue at hand that i'm trying to solve.

there's a certain command that i need to execute 10 minutes after boot.
how can i set that? im not very expert with cron jobs but can it be done 
that way? i know that cronjob works on specified time but how can i set 
it to run with '10 min after startup" as a condition ?
