--- Comment #2 from Hristo Venev <mustrumr97 at gmail dot com> ---
Am I very stupid, or is
#include <mutex>
#include <chrono>
using Clock=std::chrono::steady_clock;
int main(){
std::timed_mutex m;
m.lock();
Clock::time_point tp=Clock::now()+std::chrono::seconds(2);
if(m.try_lock_until(tp)) return 1;
return 0;
}
supposed to run for ~2s and return 0?
With clang++ -stdlib=libc++ it works as I expect.
With clang++ -stdlib=libstdc++ and with g++ it returns 1 after 0.001s.
The result is the same for std::chrono::high_resolution_clock.
The test from cppreference.com is very similar.

What the hell is going on?
