    Exemple

    #include <chrono>
#include <iostream>
int main()
{
    std::chrono::milliseconds ms{3}; // 3 milliseconds
    // 6000 microseconds constructed from 3 milliseconds
    std::chrono::microseconds us = 2*ms;
    // 30Hz clock using fractional ticks
    std::chrono::duration<double, std::ratio<1, 30>> hz30(3.5);

    std::cout <<  "3 ms duration has " << ms.count() << " ticks\n"
              <<  "6000 us duration has " << us.count() << " ticks\n"
              <<  "3.5 30Hz duration has " << hz30.count() << " ticks\n";       
}

    Résultat : 

    3 ms duration has 3 ticks
6000 us duration has 6000 ticks
3.5 30Hz duration has 3.5 ticks
