bytes 39-3F:
7DDh = 2013
01h = 1 (January)
09h = 9 0Bh = 11
16h = 22 00h = 0
2Ch = 44 27h = 39
0Dh = 13 34h = 52

So the first file was created on the 09-Jan-2013 at 22:44:13 while yours one - on the 11-Jan-2013 at 0:39:52
GMAPtool could help to make it clear for sure

As for the first two different bytes - i don't care. Maybe a checksum or something else.
