Returns the time the file was last accessed, or &false; in case of
|
|
|
|
|
an error. The time is returned as a Unix timestamp.

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 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.

This function will not work on <link
|
|
|
|
|
linkend="features.remote-files">remote files</link>; the file to
|
|
|
|
|
be examined must be accessible via the server's filesystem.
