HomeBackend DevelopmentPython Tutorial详解Python中time()方法的使用的教程

 time()方法返回时间,在UTC时代以秒表示浮点数。

注意:尽管在时间总是返回作为一个浮点数,并不是所有的系统提供时间超过1秒精度。虽然这个函数正常返回非递减的值,就可以在系统时钟已经回来了两次调用期间返回比以前调用一个较低的值。
语法

以下是time()方法的语法:

参数

  •     NA

返回值

此方法返回的时间,因为时代以秒表示浮点数(在UTC)。
例子

下面的例子显示time()方法的使用。

#!/usr/bin/python
import time

print "time.time(): %f " % time.time()
print time.localtime( time.time() )
print time.asctime( time.localtime(time.time()) )

当我们运行上面的程序,它会产生以下结果:

time.time(): 1234892919.655932
