time.clock_settime_ns() method of Time module is used to set the time (in nanoseconds) of the specified clock clk_id. Basically, clk_id is a integer value which represents the id of the clock. This method is similar to time.clock_settime() method which is used to set time of the specified clock clk_id but in fractional seconds.
Syntax: time.clock_settime_ns(clk_id, nanoseconds)
Parameters:
clk_id: A clk_id constant or an integer value representing clk_id of the clock.Return type: This method does not return any value.
Code: Use of time.clock_settime_ns() method
# Python program to explain time.clock_settime_ns() method   # importing time module import time     # clk_id for System-wide real-time clock clk_id = time.CLOCK_REALTIME     # Get the current value of # system-wide real-time clock (in nanoseconds) # using time.clock_gettime_ns() method t = time.clock_gettime_ns(clk_id)   print("Current value of system-wide real-time clock: % d nanoseconds" % t)   # Set the new value of # time (in nanoseconds) for # System-wide real-time clock # using time.clock_settime_ns() method nanosecs = 10000000time.clock_settime(clk_id, nanosecs)   print("\nTime modified")     # Get the modified value of # system-wide real-time clock (in nanoseconds) # using time.clock_gettime_ns() method t = time.clock_gettime_ns(clk_id) print("\nCurrent value of system-wide real-time clock: % d nanoseconds" % t) |
Output:
Current value of system-wide real-time clock: 1568621304462590132 nanoseconds Time modified Current value of system-wide real-time clock: 10000000000180111 nanoseconds
