12728	BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC incompatible with timed_wait	Roger Karis <rkaris@…>	Anthony Williams	"If BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC is defined, timed_wait functions wait much longer than expected.

To reproduce:

{{{
#define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

#include <boost/date_time.hpp>
#include <boost/thread.hpp>

int main(int argc, char** argv)
{
    boost::condition_variable c;
    boost::mutex m;
    boost::unique_lock<boost::mutex> l(m);

    boost::system_time const timeout = boost::get_system_time() + boost::posix_time::milliseconds(500);

    c.timed_wait(l, timeout); // Waits for a long time
    c.timed_wait(l, boost::posix_time::milliseconds(500)); // Waits for an equally long time

    return 0;
}
}}}

These functions (along with other timed_ functions) are deprecated but are currently still allowed to be used in conjunction with BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC."	Bugs	closed	To Be Determined	thread	Boost 1.63.0	Problem	wontfix
