CPU seconds calculation?

Hi, I just signed up so that I can learn python web app development from my chromebook. I was doing the Tutorial for Python Beginners and have run print("Hello World") and done the new file with print("Hello, another world") parts. It shows that I have used 2.7 CPU seconds just from that. Is this normal? or is something woefully wrong with the calculation/display/service?

That does seem a little high. Will you keep an eye on it for the rest of the day, and let us know how things progress?
