You want to avoid this at all cost, so if you do this, you probably went somewhere wrong earlier.

Why do you want to do this?

here is the code using the USER_LOCALE
function ConvertDate(aDateString: string): TDateTime;
var aMonth, aYear, aDay: Word;
  I: Integer;
  Temp: string;
  fmt: TFormatSettings;
begin
  GetLocaleFormatSettings(LOCALE_USER_DEFAULT, fmt);
  aMonth := 1;
  Temp := Copy(aDateString, 1, Pos(' ', aDateString)-1);
  for I := 2 to 12 do
    if SameText(Temp, fmt.LongMonthNames[I]) then
    begin
      aMonth := I;
      Break;
    end;
  Temp := Copy(aDateString, Pos(' ', aDateString)+1, 2);
  if Temp[2] = ',' then
    Delete(Temp, 2, 1);
  aDay := StrToInt(Temp);
  Temp := RightStr(Trim(aDateString), 4);
  aYear := StrToInt(Temp);
  Result := EncodeDate(aYear, aMonth, aDay);
end;
 
procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(FormatDateTime('DD/MM/YYYY', ConvertDate('November 3, 2008')));
end;
