Python time.clock_settime_ns()用法及代码示例

time.clock_settime_ns()时间模块的方法用于设置指定时钟的时间(以纳秒为单位)clk_id。本质上，clk_id是一个整数值，代表时钟的ID。这种方法类似于time.clock_settime()用于设置指定时钟的时间的方法clk_id但几分之一秒。

用法： time.clock_settime_ns(clk_id, nanoseconds)

参数：
clk_id:clk_id常数或代表时钟clk_id的整数值。

返回类型：此方法不返回任何值。

代码:用于time.clock_settime_ns()方法

# 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 = 10000000
time.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)

输出：

Current value of system-wide real-time clock:1568621304462590132 nanoseconds

Time  modified

Current value of system-wide real-time clock:10000000000180111 nanoseconds
