Hi,

forgive me for asking the obvious, but I fail to see how to get timing
information from the thread_clock?

I can call thread_clock::now() to get time_point objects, e.g.

  boost::chrono::thread_clock threadClock;

  boost::chrono::thread_clock::time_point start = threadClock.now();
  [...]
  boost::chrono::thread_clock::time_point end = threadClock.now();


But how do I get to the actual CPU milliseconds (or other units?) used
by the current thread between end and start?
    

You can use boost::duration_cast to convert the thread_clock::duration into whatever units you desire.  This facility will round down (truncate) if an exact conversion is not possible.  Ex:
