    Note: In most Unix filesystems, a file is considered changed when its
    inode data is changed; that is, when the permissions, owner, group, or
    other metadata from the inode is updated. See also
    <function>filemtime</function> (which is what you want to use when you
    want to create "Last Modified" footers on web pages) and
    <function>fileatime</function>.
   </para>
  </note>
  <note>
   <para>
    Note also that in some Unix texts the ctime of a file is referred to as
    being the creation time of the file. This is wrong. There is no creation
    time for Unix files in most Unix filesystems.
