The string output using tshark -Tfields is clipping 64bit fields to 32bit.
As an example I attached a packet of the gvsp protocol using a FT_UINT64 for a
timestamp field.
1) tree output:
tshark.exe -r ft_uint64.pcapng -V -O gvsp
Frame 1: 86 bytes on wire (688 bits), 86 bytes captured (688 bits) on interface

-- only the lower 32bit are available.
I will provide a patch. ft-integer and to_str are involved
