OK, I'm assuming you're referring to
http://www.vssmonitoring.com/customers/time_stamping.asp
so this is similar to, for example, what I infer the Gigamon people are doing
(see epan/dissectors/packet-gmhdr.c).
However, the description given there seems to indicate that it's not done the
same way the Gigamon people do it - it just adds, between the end of the packet
payload and the CRC, a trailer with the time stamp information, without
changing the headers or payload. *That* cannot be handled with a dissector
plugin; it would require modifications at the capture level.
