My T watches the clock, but like stopdog says, he's good at it so it isn't obtrusive. It sounds like the OP's T was very obviously continuously checking the time like there was someplace he needed to be. That would be more bothersome, but my T is pretty good about telling me if he does have to cut and run right at the end of session, so it isn't some sort of mystery. Normally he doesn't, but of course those things will come up. By my T just giving me a head's up at the beginning of session, it helps explain if I do notice a bit more clock watching than normal.
