Milestone:  To Be Determined  |   Component:  chrono      
  Version:  Boost 1.47.0      |    Severity:  Optimization
 Keywords:                    |  
------------------------------+---------------------------------------------
 The implementation of process_real_cpu_clock::now() uses the system
 ::times() function which is twice slower than clock(). In addition the
 time given by times is not related to the process lifetime but the system
 lifetime and the resolution is also twice better.
