        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";
    }

Output:

    3 ms duration has 3 ticks
    6000 us duration has 6000 ticks
