Allright... I checked around a lot of DATE and TIME routines, and came up
with this, taken from about three different routines. This routine works,
as far as I know, and I've implemented it successfully into my own code.
If anyone knows that this routine has a bug in it, please let me know.

This procedure uses the Julian calander mathmatical equasions to convert
two dates and give the # of days inbetween. If anyone knows a faster way
of writing this procedure, please let me know.
}

type
string80=string[80];

var
_retval:integer;

procedure check_date(stream1,stream2:string80);
var
internal1,internal2:longint;
JNUM:real;
cd,month,day,year: integer;
out:string[25];

function Jul( mo, da, yr: integer): real;
var
i, j, k, j2, ju: real;
begin
i := yr;     j := mo;     k := da;
j2 := int( (j - 14)/12 );
ju := k - 32075 + int(1461 * ( i + 4800 + j2 ) / 4 );
ju := ju + int( 367 * (j - 2 - j2 * 12) / 12);
ju := ju - int(3 * int( (i + 4900 + j2) / 100) / 4);
Jul := ju;
end;

begin
out:=copy(stream1,1,2);
if copy(out,1,1)='0' then delete(out,1,1);
val(out,month,cd);
out:=copy(stream1,4,2);
if copy(out,1,1)='0' then delete(out,1,1);
