Comment:

 Hi,

 you are right that there is an inconsistency I need to document.

 The correct behavior is, following the standard, to don't initialize it. I
 received a request to be able to initialize it a zero.

 I'm really sorry, but I would not initialize it in c++11. I could add a
 compiler flag to force the initialization.


 {{{
 #if  defined   BOOST_NO_CXX11_DEFAULTED_FUNCTIONS || \
      defined   BOOST_CHRONO_DURATION_DEFAULTS_TO_ZERO
         BOOST_FORCEINLINE BOOST_CONSTEXPR
         duration() : rep_(duration_values<rep>::zero()) { }
 #else
         BOOST_CONSTEXPR duration() BOOST_NOEXCEPT {};
 #endif
 }}}
