The DDO interface could use the option to have an in-game clock that keeps the player's RL time (or a different time (s)he sets it to). I'm not asking for the game to be flipped upside down but for a simple clock function with all the power of a wrist watch.
By adding a clock to the interface DDO would look a little slicker and it would help players keep track of time sensitive things both in game and out. this little bit of consideration would go a long way.
