EDIT: The petition site says, "SIGNATURES NEEDED BY AUGUST 17, 2012 TO REACH GOAL OF 25,000" for a current petition. So it is ambiguous. But I doubt any malfeasance. As the parent poster says, it is likely just a function of the website design.

Yes: it might be nice to say "expires at exactly 16:25:43.642109 UTC on Aug 9 2012", but for most use cases "expires on 8/9/2012" is considered fine. With this interpretation, even if the website said "August 9th", you can still argue that it was being fair and even correct, albeit confusing and bothersome in a way that will certainly have caused some people to think there was more time when there wasn't.
as opposed to: expire it 30 days from the start of the day that its created
the former seems simpler to me and more likely
