scheduled content

I'm simply wanting to have the ability to make a revision to existing, published content and then have that revision take effect on the site at the date/time specified. Currently, when I make a revision to existing content, a message appears on the live page saying "this content will be available..." (whenever I set the date of the update). I want the existing content to look normal - and then simply change to the revised content when specified. Can this plugin do that?
