Or, knowing more now, perhaps I am closer to being able to do that. More info:

ZIP files look like this for each file in there (Local file header)::
> 504b0304[*header signature]0a00[min. ver. needed]0000[*bit flag]
> 0000[compression method, none in this case]
> 92bd[mtime]fa40[mdate]39f4c8a1[crc32]
CRC32 of that file is
> a1 c8 f4 39
but it uses reverse byte order ("little Endian"?) so it's 
> 39 f4 c8 a1

The question here is about converting the bytes timestamps back and forth. 92 bd [mtime] fa 40 [mdate] = normal order
> bd 92 [mtime] 40 fa [mdate]
which is what?...
