Yes and no: Yes, it could be possible to get the time the process was active, but no,
it is not possible to get an accurate time because you still have the process mamager
overhead (switching, getting the time etc.) and so the longer the rendering the larger
the overhead. I would guess it is a few seconds per hour and you would not have them
with a single task system like DOS (ok, its interrupts will add a few microseconds as
well...).

However, you are right that using the CPU usage would be much more accurate than the
current implementation, but image all the programming overhead - there are simply more
important things to do than to implement a better working render time calculator...
