Get millisecond part of time

Question

I need to get milliseconds from the timer

    // get timer part
    time_t timer = time(NULL);
    struct tm now = *localtime( &timer );
    char timesta         


        

Answer 1

#include 

typedef std::chrono::system_clock Clock;

auto now = Clock::now();
auto seconds = std::chrono::time_point_cast(now);
auto fraction = now - seconds;
time_t cnow = Clock::to_time_t(now);

Then you can print out the time_t with seconds precision and then print whatever the fraction represents. Could be milliseconds, microseconds, or something else. To specifically get milliseconds:

auto milliseconds = std::chrono::duration_cast(fraction);
std::cout << milliseconds.count() << '\n';
