You're out of luck, there isn't a tracker for that built in.
That would be cool though. Although I don't think I'd want to know.
I'm going to go looking for a third party thing that only does time when you're watching something or typing etc. I'll just start the time now.

There is. Install S.M.A.R.T Utility for Mac, install the driver and then check the HDD Power-On time. It will show you the amount of time the system has been running in hours since it was purchased.
Some exceptions:
- If you leave it on overnight very often, the number will be inflated.
- HDD was replaced or SMART data was wiped by Apple during a Genius Bar appointment.
I was unaware.
