{{{

outputs

{{{

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. "	Bugs	closed	Boost 1.56.0	chrono	Boost 1.54.0	Problem	fixed
