#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.
