Is there a way to tell how many hours you've played Sims 3?

I have the Ambitons and Late Night expansions. It there a way to see how many hours I've played? Also, once I installed Late Night it's been slightly buggy. Time will freeze when not on pause, I have paparazzi and celebrity points (which I can't figure out how to track) but there were no new buildings added. I haven't begun a new game since the last expansion, but I plan to in a few days.
