I'm not aware of any other AHs that do what the OP found Sotherbys and Christies do, but Clean Sweep Auctions does the opposite of what the OP suggested and increases their BP as it gets later at night. I assume the goal is to get the auction to finally end since bidding later at night becomes more expensive (for everyone whether or not they are aware of it or factor it into their bidding).
15. BIDS PLACED AFTER 1:30 AM EST ARE SUBJECT TO A 5% ADDITIONAL BUYERS PREMIUM, 10% AFTER 2:30 AM EST; MAXIMUM BIDS PLACED BEFORE THIS TIME ARE EXEMPT FROM THIS.
