오랜만에 C++ - chrono

#include <chrono>

std::chrono::system_clock::time_point starTime;
std::chrono::system_clock::time_point endTime;



* 특정 시간 동안

std::chrono::seconds three(3);

startTime = std::chrono::system_clock::now();

std::this_thread::sleep_for(three);

endTime = std::chrono::system_clock::now();

std::chrono::seconds during = std::chrono::duration_cast<std::chrono::seconds>(endTime - startTime);

std::cout << during.count() << std::endl;




* 특정 시간 이후에..

std::chrono::seconds five(5);

startTime = std::chrono::system_clock::now();

std::this_thread::sleep_until( startTime + five );

endTime = std::chrono::system_clock::now();

during = std::chrono::duration_cast<std::chrono::seconds>(endTime - startTime);

std::cout << during.count() << std::endl;
