    Bug in Ad pruning SQL in CP 3.1.6

    I believe there is a bug in the SQL statement to select ID's of posts to prune in CP 3.1.6. The existing SQL from theme-cron.php is:

    Code:
    SELECT wp_posts.ID FROM wp_posts LEFT JOIN wp_postmeta ON wp_posts.ID = wp_postmeta.post_id WHERE wp_postmeta.meta_key = 'cp_sys_expire_date' AND timediff(STR_TO_DATE(wp_postmeta.meta_value, '%m/%d/%Y %H:%i:%s'), now()) <= 0 AND wp_posts.post_status = 'publish' AND wp_posts.post_type = 'ad_listing';
    the problem is the timediff(STR_TO_DATE(wp_postmeta.meta_value, '%m/%d/%Y %H:%i:%s'), now()) <= 0 part. timediff() returns a value in time format, like '-04:05:23' and this value with colons, when compared to integer 0 produces an error.

    I corrected this using a straight ahead magnitude comparison between the expire data and now(). Here is my modified sql for pruning ads:

    Code:
    $qryToString = "SELECT $wpdb->posts.ID FROM $wpdb->posts
            LEFT JOIN $wpdb->postmeta ON $wpdb->posts.ID = $wpdb->postmeta.post_id
            WHERE $wpdb->postmeta.meta_key = 'cp_sys_expire_date'
            AND STR_TO_DATE($wpdb->postmeta.meta_value, '%m/%d/%Y %H:%i:%s') <= now()
            AND $wpdb->posts.post_status = 'publish' AND $wpdb->posts.post_type = '".APP_POST_TYPE."'";
    This code works for me. Do you see any downsides to this modification?
