For the most part it really doesn't matter. If you are worried about getting your listings pulled due to VERO it can still happen. Anybody can scan the completed listings and then notify Ebay. You could get a takedown a week after the auction closes.
Yes,felon is right,if ebay get too much complaint about your listing ,even from your competior,ebay will auction for your listing soon.It doesnot matter the working time too much,but you can make your list on short time bidding,just 1 day or 2 days
You might not be able to hide but you might be able to prolong your listings by posting at night or on the weekend which can result in more sales before your listing get's pulled.
