How to do it...

To work with time intervals, use the following:

• std::chrono::duration typedefs for hours, minutes, seconds, milliseconds, microseconds, and nanoseconds:

        std::chrono::hours        half_day(12);        std::chrono::minutes      half_hour(30);        std::chrono::seconds      half_minute(30);        std::chrono::milliseconds half_second(500);        std::chrono::microseconds half_millisecond(500);        std::chrono::nanoseconds  half_microsecond(500);

• Use the standard user-defined literal operators from C++14, available in the namespace std::chrono_literals for creating durations of hours, minutes, seconds, milliseconds, microseconds, and nanoseconds:

        using namespace std::chrono_literals;        auto half_day         = 12h;        auto half_hour        = 30min;        auto half_minute      = 30s; auto half_second ...
