Hi, as I understood the problem you lose up to 7 hours but the end time is what you would expect e.g. 7 or 10 days after posting so that you do not need to allow for this delay.
Therefore as most bidding seems to occur in the closing minutes is it really a problem ?
Unfortunately someone has to tackle fraud on eBay and the only ones who can do that are eBay although I must admit these time delays do appear to be excessive.
