Recording render times?

RonH1932

I'm sure there's a simple answer to this but I don't know it. The progress window times a render as the scene is rendering but disappears when the render is finished, taking the "stopwatch" with it. I'm trying to learn to reduce rendering time and I want to keep track of each render, but if I'm away from the computer when a render (finally) finishes the timer has disappeared when I return. How do I get back the time of the last render?
