Hmmm... Sounds like something is caching your FT display (at least initially) in order to display the forums as if today were 5/1.

Try clearing out your browser's cache and any temporary internet files and reloading the site. Hold down the shift key while you reload the site to force the browser to grab the latest version off our server.

Sorry about the problems; we haven't done anything to "roll back" the date to 5/1, and I can't seem to duplicate the error at this end.
