Sorry for asking this, but what the heck difference does a time zone make? The auction ends at the same time, everywhere, just like it does now.

If you mean it's 7 pm one place and 9 pm in another, it's still the same moment in time. Same as it is now.

Meanwhile, it's probably a programming nightmare and I don't get upset when someone beats me, so this is all a theoretical discussion.

If I had the energy and motivation, I'd try to snipe an auction, but I'm pretty boring and dull. I just bid my Max. price and let the cards fall. Sometimes that bid is enough and I'm forced to part with my money for some nice coin, token, book, chip or computer junk. LOL
