I've occasionally wondered how fleabay manages to be "fair" and "accurate" at the end of auctions, especially with sniping from different continents. I've no real way of telling whether it actually does possess those properties.

The HFT mob has timescales a thousand times worse, and they have the inclination and money to be sure :)

"fair" and "accurate", or just "fairly accurate"? I expect fairly accurate is good enough. Most of the latencies are beyond their control, so they really can't do better. It be happy if e-bay just sorted out their broken language selection system.

Is there a rule for auction sites? My guess is that Ebay's software just doesn't care and rounds timestamps to the nearest second. It simply is not a problem.

I haven't noticed a problem, which is a very weak statement.
I haven't seen reports of a problem, which is a slightly less weak statement.

Once again you are trying to create a problem which just isn't there. First come up with a legal requirement that states how auctions are supposed to be held timing wise. If that exists, you have a framework you can build a problem definition upon. But if that isn't there, there simply is no problem because there are no requirements. IOW: a problem can not exist without requirements.

If you go to Ebay's website and read about auction timing, you'll see they specify the time an auction runs in units of 1 minute. Basically it means whatever works best for Ebay goes.
