Python | time.time_ns() method Last Updated : 05 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.time_ns() method of Time module is used to get the time in nanoseconds since the epoch. To get the time in seconds since the epoch, we can use time.time() method. The epoch is the point where the time starts and is platform dependent. On Windows and most Unix systems, the epoch is January 1, 1970, 00:00:00 (UTC) and leap seconds are not counted towards the time in seconds since the epoch. To check what the epoch is on a given platform we can use time.gmtime(0). Note: time.time_ns() method is new in Python version 3.7 Syntax: time.time_ns() Parameter: No parameter is required. Return type: This method returns an integer value which represents the time in nanoseconds since the epoch. Code: Use of time.time_ns() method Python3 # Python program to explain time.time_ns() method # importing time module import time # Get the epoch obj = time.gmtime(0) epoch = time.asctime(obj) print("epoch is:", epoch) # Get the time in seconds # since the epoch # using time.time() method time_sec = time.time() # Get the time in nanoseconds # since the epoch # using time.time_ns() method time_nanosec = time.time_ns() # Print the time # in seconds since the epoch print("Time in seconds since the epoch:", time_sec) # Print the time # in nanoseconds since the epoch print("Time in nanoseconds since the epoch:", time_nanosec) Output: epoch is: Thu Jan 1 00:00:00 1970 Time in seconds since the epoch: 1567451658.4676464 Time in nanoseconds since the epoch: 1567451658467647709 References: https://docs.python.org/3/library/time.html#time.time_ns Comment More infoAdvertise with us Next Article Python | time.time_ns() method I ihritik Follow Improve Article Tags : Python python-utility Practice Tags : python Similar Reads Python | time.gmtime() method Time module in Python provides various time-related functions. This module comes under Pythonâs standard utility modules. time.gmtime() method of Time module is used to convert a time expressed in seconds since the epoch to a time.struct_time object in UTC in which tm_isdst attribute is always 0. To 3 min read Python | time.localtime() method Time module in Python provides handy tools to work with time-related tasks. One of its most useful functions is time.localtime(), which converts time expressed in seconds since the epoch (January 1, 1970) into a local time representation. It returns a time.struct_time object, which is a tuple-like s 2 min read Python | time.mktime() method time.mktime() method of Time module is used to convert a time.struct_time object or a tuple containing 9 elements corresponding to time.struct_time object to time in seconds passed since epoch in local time. This method is the inverse function of time.localtime() which converts the time expressed in 4 min read Python | time.monotonic() method Python time.monotonic() method is used to get the value of a monotonic clock. A monotonic clock is a clock that can not go backward. As the reference point of the returned value of the monotonic clock is undefined, only the difference between the results of consecutive calls is valid.

This module comes under Pythonâs standard utility modules. time.monotonic_ns() method of time module in Python is used to get the value of a monotonic clock in nanoseconds. This method is similar to time.monotonic() method which returns 3 min read time.perf_counter() function in Python The time module provides various time-related functions. We must import the time module before using perf_counter() so we can access the function without throwing any errors.The perf_counter() function always returns the float value of time in seconds. Return the value (in fractional seconds) of a p 4 min read Python time.perf_counter_ns() Function Python time.perf_counter_ns() function gives the integer value of time in nanoseconds. Syntax: from time import perf_counter_ns We can find the elapsed time by using start and stop functions. We can also find the elapsed time during the whole program by subtracting stoptime and starttime Example 1: 1 min read time.process_time() function in Python time.process_time() is a function in Pythonâs time module that returns the CPU time used by the current process as a floating-point number in seconds. Unlike time.time(), which measures real (wall-clock) time, time.process_time() focuses on the time spent by the CPU executing the process, excluding 4 min read Python | time.process_time_ns() method Time module in Python provides various time-related functions. This module comes under Pythonâs standard utility modules. time.process_time_ns() method of time module in Python is used to get the sum of the system and user CPU time of the current process in nanoseconds. This method does not include 5 min read time.sleep() in Python Python time sleep() function suspends execution for the given number of seconds. Syntax of time sleep() Syntax : sleep(sec) Parameters : sec : Number of seconds for which the code is required to be stopped. Returns : VOID. Sometimes, there is a need to halt the flow of the program so that several 4 min read Like
