WebDescription The function clock_getres () finds the resolution (precision) of the specified clock clk_id, and, if res is non-NULL, stores it in the struct timespec pointed to by res. The resolution of clocks depends on the implementation and cannot be configured by a particular process. WebThe high resolution timer code does not support SMP machines which have only global clock event devices. The support of such hardware would involve IPI calls when an interrupt happens. The overhead would be much larger than the benefit. WebApr 8, 2024 · The high resolution timers are needed for accurate benchmarking instead of the less precise and non-monotonic Date timestamps.

WebFirst, the GetSystemTime* calls are the only Win32 APIs providing the system's time. This time has a fairly coarse granularity, as most applications do not need the overhead required to maintain a higher resolution. Time is (likely) stored internally as a 64-bit count of milliseconds. Calling timeGetTime gets the low order 32 bits. WebMay 6, 2024 · Since the High Resolution Time API is essentially an abstraction over operating system and hardware clocks, I looked further into what's currently possible on widely deployed platforms.
