A WordPress plugin aimed primarily at events sites, where you want to be able to timestamp posts in the future but have them appear immediately (by default, WordPress will not display a future timestamped post until its go-live date rolls around). This plugin sets the post_status field to “publish” rather than “future” when publishing a post, even if its timestamp is in the future. Written by Ryan Boren and modified by Andrew Nacin – I’m just hosting it.
Instructions: Install via Add Plugins, or place future-post.php in your plugins directory and activate. Write a post with a future timestamp and hit publish. Notice that it goes live on your site immediately.
Note: This seemingly simple plugin was graciously written by the magical Ryan Boren when I was facing a deadline. He doesn’t have time to maintain/host it, so I agreed to. The plugin was later updated by Andrew Nacin to work with WP 3.5+
