Hi folks,

can a few of you folks please run the following little program on your 
computers and report the time it takes to run?

--------------------------------------------------
#include <chrono>
#include <thread>
#include <iostream>

inline void Delay(unsigned int msec)
{
     std::this_thread::sleep_for(std::chrono::milliseconds(msec));
}

int main()
{
     int count =  1000;
     for (int i = 0; i < count; ++i)
     {
         Delay(1);
     }
     std::cout << "Done." << std::endl;
}
--------------------------------------------------

On Windows Subsystem For Linux I see results like the following:

real    0m1.782s
user    0m0.000s
sys     0m0.000s

But as I presume this is using the Windows scheduler, I expect that 
genuine Linux systems may behave differently, and I'm also interested in 
other platforms (Mac, maybe BSD if some of you folks are using that, or 
actually any system you can get your hands on.)

I have also reason to believe that results may differ between compilers. 
Using g++ 5.4.0 here.
