My T has one clock for her and one for the client and we have already discussed them few times... One thing is that sometimes the client clock is turned so that I cannot see the time, t annoys me but I use then my own watch. However, I mentioned it once, and my T said that she never turns the clock away from the client but sometimes the cleaning lady does it as she thinks that the clock should face T when she sits at her desk, and if noone tells T about it sometimes she might not realize it for few hours or even days...
Another thing is that whenever I see that time is up, my T says that according to her clock there are still 2-3 minutes and that she doesn't understand them (clocks) because they both are set based on the satellite but they are still not synchronized and it is not possible to synchronize them manually. T has said that she's already thought about switching the clocks before my sessions but she didn't do that
