Description
int fileatime (string filename)
Returns the time the file was last accessed, or false in case of
an error. The time is returned as a Unix timestamp.
The results of this function are cached. See
clearstatcache() for more details.
Note: The atime of a file is supposed to change whenever
the data blocks of a file are being read. This can be
costly performancewise when an appliation 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.
