#12728: BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC incompatible with timed_wait
------------------------------------+----------------------
 Reporter:  Roger Karis <rkaris@…>  |      Owner:  anthonyw
     Type:  Bugs                    |     Status:  new
Milestone:  To Be Determined        |  Component:  thread
  Version:  Boost 1.63.0            |   Severity:  Problem
 Keywords:                          |
------------------------------------+----------------------
 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.
