WebbEven if the resolution is high (a small number), all it means is that you'll be able to specify the arguments to clock_gettime () and clock_nanosleep () with that resolution. The system might not actually be able to measure events at that resolution, and the various overheads and the overall system load are certain to affect any timings. Webbsteady_clock. Class std::chrono::steady_clock represents a monotonic clock. The time points of this clock cannot decrease as physical time moves forward and the time between ticks of this clock is constant. This clock is not related to wall clock time (for example, it can be time since last reboot), and is most suitable for measuring intervals.
