@Stehfee,
Well, most I can say is just keep trying to think of different ways that humans communicate with each other. One should relate to the position of hands on a clock.
I will say too. I don't see any connection between the answer and the shop that the LC author linked to . Except that it sells clocks, I guess. So maybe I'm wrong (but I really don't think so), because I would have thought there was reason they wanted us to go see Alabaster Chesterdrawers.
