Have a look at Engine/PixelSampler/TimeViewSampler.cc

This computes the time to render a group of pixels.  You could
probably use something similar for the SingleSampler or the
JitterSampler to compute the color only for a packet.  Note that you
should use the CPUTime::currentSeconds, so that it will scale across
multiple processors.
