    <para>
     Attempts to set the access and modification time of the file named by
     filename to the value given by time. If the option <parameter>time</parameter> is not
     given, uses the present time. This is equivalent to what utime
     (sometimes referred to as utimes) does. If the third option
     <parameter>atime</parameter> is present, the access time of the given
     filename is set to the value of <parameter>atime</parameter>. 
     Note that the access time is always modified, regardless of the number
     of parameters.
