std::this_thread::sleep_for() and GCC
Tried to write a simple timer and some code to test it by letting the program sleep for some time:
#include <chrono>
#include <thread>
Aux::Timer timer;
timer.start();
std::this_thread::sleep_for(std::chrono::milliseconds(1000));
timer.stop();
std::chrono::duration<int64_t, std::milli> t = timer.elapsed();
This gives me a compiler error:

I haven't used the <thread> library before. Can you suggest a quick fix? I'd also be happy with an alternative for testing the correctness of the timer.
Fixed the issue described here: std::this_thread::sleep_for() and GCC
with a #define _GLIBCXX_USE_NANOSLEEP 1 at the beginning of the file.
