isb_starttime and isb_endtime are written in host byte order as 64-bit number.
Looking at spec it's valid.
Please note in spec they're not divided (like timestamps in EPB) into high/low
halves.

So you need to read whole 8 bytes, and eventually swap them (if pcapng was
written on BigEndian machine).

Please reopen if you think there's still a bug in wireshark.
