Is this possible? Timer for Premiere

I was talking to a co-worker, and we were fighting about how much time a project had taken.

Then I brought up the question: What if Premiere had a time tracking function? What if it was an automatic tracker that kept the time of workflow when you were on the Premiere screen, and you could reference that for clients and/or your own use?

I feel like this is not super important, but it really is so that you have proof of how long it takes for some projects.

Sometimes you forget to check the time you started, so it's hard to say how long it really does take for longer, more complicated projects.
