 When using

 {{{
  boost::chrono::duration< boost::rational<int> >
 }}}

 as duration type, chrono_io v2 fails to build with error
 {{{
 include/boost/chrono/io/duration_units.hpp:136:91: error: invalid
 static_cast from type ‘boost::chrono::duration<boost::rational<int> >::rep
 {aka boost::rational<int>}’ to type ‘intmax_t {aka long int}’
 }}}

 while chrono_io v1 builds and works as expected.

 Here is the full compilation log for the attached example.
