This is a lightweight plugin designed to make WordPress posts expire at a set time. This was done in the simplest, most expedient manner possible so conflicts should be minimal. How it works: You can set an expiration date (aka an expiry) for a post by selecting the date and time. This uses local time, not GMT, UTC, etc. Picking a date/time is optional. When the expiration date/time have been passed the post will be moved from Published status to Draft status.
