Network Instruments Observer v9 format support needs improvements in the
following four areas:
1.) Files where the packet header and packet data are noncontiguous are handled
improperly, resulting in read misalignment and ultimately the error message,
"Observer: bad record: Invalid magic number 0xXXXXXXXX." This bug is caused by
not obeying the packet_entry_header.offset_to_frame field.
2.) Daylight savings time is not properly accounted for in files using local
time encoding.
3.) As of Observer/GigaStor v14, timestamps in the file format changed from
local time encoding to GMT encoding. Wiretap should not only support reading
both formats, but should also allow the user to select which format to write
with different file types. This should function similarly to how lipbpcap
supports both microsecond and nanosecond timestamp granularities with different
file types.
4.) The wtap_dumper.bytes_dumped field is not being properly incremented as
data is written to files.
