Looks like your eyesight is just fine Hosman. Do a right click on the description and select properties. It was modified on 9/9/11. The auction ended on 9/8/11.
You can also see it if you go to your browser, select View, then select Source. In the resulting window select Edit, then select Time/Date. You'll see when it was last modified at the beginning of the HTML code. If I am not mistaken, a saavy seller is able to alter the date and time manually in the source code by doing the same thing and editing the code, but it looks like your seller didn't think of that. If you want to pursue this, you might want to save some screen captures.
