COMPUTE DATE

            [SIC\]COMPUTE Modification_Date DATE Filename

        Return the last modification date of the file Filename into the  integer
        variable  Modification_Date.  Used  in procedures to check when file has
        last been changed.

        If the output variable is a 4-bytes integer (Fortran I*4), returned val-
        ue  is  in  seconds  since 01-jan-1970. As the value will overflow after
        19-JAN-2038, this syntax is obsolescent and  will  be  removed  at  some
        point.  Consider  using  I*8 output variable (in nanoseconds) or the SIC
        MODIFIED command.

        If the variable is a 8-bytes integer (Fortran I*8), returned value is in
        nanoseconds  since  01-jan-1970.  In  the latter case, your system (e.g.
        Linux >= 2.5.48) AND filesystem (e.g. ext4) must support timestamp gran-
        ularity  below  the second. If not, value precision is limited to 1 sec-
        ond.
