WebKit r35704 does not display RSS feed items in the correct order. Attached is an RSS feed that demonstrates the problem. The August 11 item is displayed before the August 12 item. Furthermore, WebKit displays the August 11 item as having the current date and time. (The item's date changes every time you refresh the feed.) Other newsreaders, such as NetNewsWire, do not have this problem. The feed is valid according to the W3C Feed Validator.
