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.

As the name suggests Python time module allows to work with time in Python. It allows functionality like getting the current time, pausing the Program from executing, etc. S 7 min read Python | time.asctime() method Python time method time.asctime() is used to convert a tuple or a time.struct_time object representing a time as returned by time.gmtime() or time.localtime() method to a string of the following form: Day Mon Date Hour:Min:Sec Year For example: Thu 08 22 10:46:56 2019Python time asctime() Syntax: ti 3 min read Python time.pthread_getcpuclockid() Function The pthread_getcpuclockid() function returns the clock id of the thread-specific CPU-time clock for the specified thread_id. The thread ids are obtained from the different threads that are running being used by that program. The thread ids can be obtained using the 'ident' field of the threading cla 2 min read Python | time.clock_getres() method Time module in Python provides various time-related functions.
