Cron fires outside of the standard WordPress loop, so $post will not be filled with any post-related data when the function is called. It should be obvious, then, that providing an ID directly isn’t referencing the non-existent $post variable which is why it works in that scenario. The best way to set post_statuses to expired … Read more

You’re looking for wp_schedule_event which hooks into the WordPress cron. Cron’s job is to run tasks periodically from the back end.
