说明：  这是一个简单的自动定时运行，通过它，可以做很多需要定时执行的事，比如定时每天自动采集，这样就无需站长天天到网站上点一下采集了。在定时执行函数中可以写任何你要定时执行的代码，需要什么应用自己发挥吧。
(This is a simple automatic timed run through it, you can do a lot of things to be automatically executed, such as regular daily collected automatically, so you do not need every day to the site webmaster collected on tap. In the regular implementation of the function can write whatever you want to regularly execute code, what applications need to play it yourself.)
