[M Holt <m.iostreams@xxxxxxxxx>]

I tried the capture in 1.07 and 1.2.1, and got the same results.
I have used both Windows and Ubuntu 9.04 on a 32 bit system to view the file.
I did some google searches and I am not able to find anything else on the issue.

So, not much help, but I am *guessing* that the problem is in the capture.
Unfortunately, I couldn't begin to say where.

I got this capture from my accelerator card, that i am using for monitoring
data capture which supports nano second time stamp. but the problem is here
when i used winpcap lib functions to parse the packets it is showing perfect
time stamp as per expected in the log i have attached below. and the nano
second time and second time is perfectly calculated by card that i watch
from the capture file using the winpcap api.

As per my knowledge, wireshark is modifying the time to system time, and
then put the fist packet arrival time t0 0.000000000 in display and then
so on.

is the problem is in wireshark or in my capture file???

the system i am using is ubutnu9.04, 64bit server.
