Processor time used by Emacs

Is there a way in Emacs Lisp to find out the amount of processor time
(perhaps separated into user/system time) spent by Emacs?

For example, if there was such a function called processor-time, this
should return (close to) 0:

        (let ((start (processor-time)))
          (sleep-for 10)
          (- (processor-time) start))

, whereas current-time would indicate that ten seconds passed
