不管刷新、重新访问页面多少次，页面显示时间2013年12月05日 20:03:31总是不变。
这是为什么呢？

Note:
The atime of a file is supposed to change whenever the data blocks of a file are being read. This can be costly performance-wise when an application regularly accesses a very large number of files or directories.
Some Unix filesystems can be mounted with atime updates disabled to increase the performance of such applications; USENET news spools are a common example. On such filesystems this function will be useless.
不同的文件系统使用都会不同的..
可以试下clearstatcache() 清除下缓存再读
你代码写的有问题，清楚缓存，访问时间还是没有变化。
