    I believe that you would simply set 2 hours, as in:

    * */2 * * * root /usr/libexec/locate.updatedb

    That would run the script in /usr/libexec/ called "locate.updatedb"
    every 2 hours, taking as long as it needs to.

    Please correct me if anyone knows more about it than I do.
    Thanks...
