the answer is the AOM clock! this interesting little scenario starts at 12 midnight and continues to tell the correct time (if you started it at 12 midnight) until you quit! this is a good example of what you can do with quest vars.
NEW V1 - you can now set the starting hour!
comming soon V2 - in V2 ill try and let you set the minutes
(possible version 3 will make it a menu background.)
