Comment (by viboes):

 Maybe the problem is that the system_clock is taken too early

 Coulod you try


 {{{
           typename Clock::time_point  c_now = Clock::now();
           return try_join_until(system_clock::now() + ceil<nanoseconds>(t
 - c_now));
 }}}

 instead of

 {{{
           system_clock::time_point     s_now = system_clock::now();
           typename Clock::time_point  c_now = Clock::now();
           return try_join_until(s_now + ceil<nanoseconds>(t - c_now));
 }}}
