There are 9 time zones in the US and depending on what your buying in the eu, jp, etc, I'm not going to be up to deal with the end of an auction, either too early too late or you know I have a real efing job and i'm doing something. Having ends of auction require you to be around means you lock out large parts of the market.
It doesn't need to!
If the winner, instead of paying what they bid, pays what the second-highest bidder bid (and bids are secret until someone exceeds them) then the incentives change. Everyone is incented to bid what it is worth to them, safely knowing (1) they won't pay more than that, (2) they will win the auction if no one outbids them, and (3) they won't pay more than necessary to win the auction.
eBay works this way (more-or-less), so you CAN (if you choose to) simply place your bid any time that is convenient and then ignore the timing of the end of the auction and all the sniping bots.
...that's what auctions are...being around to bid...
Except for sealed bid auctions. EBay doesn't do sealed bid auctions, and that's fine.
