Do you see the same thing if you capture traffic with WinDump:

    http://www.winpcap.org/windump/install/default.htm

If you run it without "-w", it'll print the time stamps of the packets.  If you
run it with "-w", it'll write out packets in libpcap format, which is also
Wireshark's format, so Wireshark can read the file.

If the same thing happens with WinDump - which I suspect it will - the problem
is a WinPcap issue (as I suspect it is), and the WinPcap developers might be
able to tell you whether the time stamps WinPcap supplies to applications using
it (such as WinDump and Wireshark's dumpcap) can go backwards when running in a
VM.  See

    http://www.winpcap.org/contact.htm

and

    http://www.winpcap.org/bugs.htm

for information on reporting bugs in WinPcap.
