Review Short PHP Script - Wordpress Cron Job

I need a WordPress Developer to review a short script and fix it if necessary. I will send the script to the chosen developer. NOTE: You will be ONLY REVIEWING the SCRIPT and Fixing it if necessary, you will NOT be writing a new script. HERE IS THE DESCRIPTION OF THE SCRIPT: I wrote a Wordpress cron job to delete temporary wishlists that are over 30 days old. The wishlists are saved as custom post types with post_type value as "wishlist". Also I'm using post_author value as 1 to only remove wishlist created by users that were not logged in (This way the wishlists in the query are only the temporary ones). I would like the cron job to run once a day and adding this to functions.php. Please write cron-123 in your bid so I know you've read this description. You must be experienced with Wordpress, Wordpress cron jobs and custom post types.
