#9342: Regression on process_cpu_clock::timepoint io on V2
------------------------------+---------------------
 Reporter:  viboes            |      Owner:  viboes
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  chrono
  Version:  Boost 1.54.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 The following example
 #include <boost/chrono/chrono_io.hpp>

 {{{
 #define BOOST_CHRONO_PROVIDES_DEPRECATED_IO_SINCE_V2_0_0

 int main() {
   std::cout<< boost::chrono::process_cpu_clock::now() << std::endl;
 }
 }}}

 outputs

 {{{
 {1383629724660000000;0;0} nanoseconds since process start-up
 }}}

 while if BOOST_CHRONO_PROVIDES_DEPRECATED_IO_SINCE_V2_0_0 is not defined,
 it outputs

 {{{
 1383629672240000000 nanoseconds since process start-up
 }}}

 A process_cpu_clock::duration::rep is a tuple like of 3 clocks real, user
 and system.

 The same problem for input. V1 manages a format {{{ {v1,v2;v3} }}}  and is
 able to restore the 3 clocks, but V2 takes only the real clock in account.
