#include <time.h>intclock_gettime(clockid_t clk_id, struct timespec* tp);可以根据需要,获取不同要求的精确时间参数:clk_id :检索和设置的clk_id指定的时钟时间。CLOCK_REALTIME:系统实时时间,随系统实时时间改变而改变,即从UTC1970-1-1 0:0:0开始计时,中间时刻如果系统时间被用户改成其他,则对应的时间...
Suspend execution of the calling thread for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. The actual suspension time may be less than that requested because any caught signal will terminate thesleep()following execution of that s...

The function then creates a pipe to link up to the stdout of the subprocess, which the function then reads into the CompletedProcess object’s stdout attribute. By the time it’s a CompletedProcess, it’s no longer a pipe, but a bytes object that can be accessed multiple times....
importtimeast t.strftime("a, %d %b %Y %H:%M:%S +0000",t.gmtime()) time.strptime(string[, format]) 把一个格式化时间字符串转化为 struct_time。实际上它和 strftime() 是逆操作。 举个例子: importtimeast t.strptime("30 Nov 14","%d %b %y")time.struct_time(tm_year=2014,tm_mon...

Python实战之数字、日期和时间的高级处理,写在前面博文为《PythonCookbook》读书后笔记整理涉及内容包括:浮点数执行指定精度的舍入运算。执行精确的浮
In this lesson, I’m going to take you through the foundational way that Python handles time, which is as a floating-point number of seconds. And to understand how that works and how that’s even possible, you’ll need to understand a concept called…
