 * The Date D is a int with 4 bytes using little endian,
 * The representation is (D+19000000).ToString -> YYYYMMDD,
 * eg: Date 07 b2 01 00 -> 111111 in little endian -> 19111111 - > 1911.11.11.
 * the null date will use 0 to pad.
 *
 * @return the date
 * @throws IOException the io exception
 * @throws ParseException the parse exception
