My T has 2 clocks as well. There's one on the wall behind the couch that she can see but I can't, and there's a little one on the table beside her chair that I can see. I hate looking at it, because time already goes too fast while I'm there, and that just reminds me just how fast the time is going. Sometimes I see her making subtle glances toward the clock, but that's more when time is coming to the end of our session, so I don't think too much of it.
