...but the edit post request on every users attempt to edit shows a log with the wrong time of day and always has.
Rooney, one thing I've noticed is that if I come back to the site, after having had it open in a different session, the time since last post doesn't update. I think its because the page loads from cache. If I refresh the page it updates.
Maybe that is completely unrelated.
Using a desktop computer and Chromium browser here. That history box is populated with the wrong date. That post got completed of revisions in minutes not hours. So Jafar, if you use a cellphone browser such as in android or I-phone you can't test it and you would have missed my point. Cellphones receive different versions of code to optimize a small screen.
