This change would be great for both buyers and sellers. An auction time could say "short" and you think you have time to go do a run. You come back and its already hit very short and you lost the bid.

By having the time displayed, you'll have a bunch of players who will calculate when the auction is going to end, and so they will come to haven at the appropriate time. A change like this will make it much easier to sell items for the right prices because everyone will know when its time to go into bid war. You'll be much less likely for an item to sell underpriced.

I have had situations where one of my items sold for unpriced on the auction house. Later I got like 3 pms saying they would have bought it at full price, but they forgot to bid on that item.

I believe that somewhere in the code you have a script that says, print "Text here'" if variable time left is less than x amount and greater than x amount. Just change some of the things around and you'll be done.
