Time module in Python provides various time-related functions. This module comes under Python’s standard utility modules.
Python3
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
# 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)
