Python | time.clock_getres() method Last Updated : 17 Sep, 2019 Comments Improve Suggest changes Like Article Like Report Time module in Python provides various time-related functions. This module comes under Python’s standard utility modules. time.clock_getres() method of Time module is used to get the resolution or precision of the specified clock clk_id. Basically, clk_id is a integer value which represents the id of the clock. Following are the constants available on UNIX platforms that can be used as value of clk_id parameter: clk_id clk_id constant Meaning 0 time.CLOCK_REALTIME System-wide real-time clock 1 time.CLOCK_PROCESS_CPUTIME_ID High-resolution per-process timer from the CPU 2 time.CLOCK_MONOTONIC It represents monotonic time since some unspecified starting point 3 time.CLOCK_THREAD_CPUTIME_ID Thread-specific CPU-time clock 4 time.CLOCK_MONOTONIC_RAW Similar to time.CLOCK_MONOTONIC, but provides access to a raw hardware-based time that is not subject to NTP adjustments Note: time.clock_getres() method is only available on UNIX-like systems. Syntax: time.clock_getres(clk_id) Parameter: clk_id: A clk_id constant or an integer value representing clk_id of the clock. Return type: This method returns a float value which represents the precision or resolution of specified clock clk_id.
