Here the datatype number is 13, instead of 12. The memory structure has been padded to a 4-byte boundary. The time bytes do not have any offset. And the century and year are represented as a single signed two byte number. Because this dump was taken on a machine with a little-endian architecture, the bytes are reversed and should be read as 7,210 or 0x7D2, which is decimal 2002. The corresponding bytes for 492 BC would be 20,254. That reverses to 254,20 or 0xFE14, which is -492 in two's complement notation. These details are of course platform specific.
