I believe it's possible that can happen if a post happens to be moved.
For example, if someone posted here today at 5:35 PM Pacific Time (which it now is), asking about the latest Google update, the post could possibly be moved over to the Google forum, and yet still show me a post here at 5:35.
This will have to be confirmed by our friendly "programming staff" of course :)
