I think cheatnsteal knows the 3 minutes rule. The auction ended 40. The problem ist, that the time shown above isn't correct right now. I also had a bid and the auction went on after the shown ending time (without any new bid!)
I justed my TV-text time, it was some seconds away from the server time shown above and this was correct.
example:
player ends: 00:03:00
I bet server time 00:00:20, real time was 00:00:00.
ending time is 00:03:00
but the auction will end real time 00:03:00, the server time shown above will be 00:03:20...
I had this problem some weeks ago.
