Actually, the auction ends at 4:20pm on a Thursday. But why does it matter if it ends on the hour or half or quarter? I would think it matters if it ended at 4:00am in the morning as opposed to 4:00 pm in the afternoon.
And how does A/S add time? Does it do it for me automatically? I don't understand.
So in my case, I should use 7-8 seconds?
btw, it's only one item.
Thanks for your help.
