Transmission Latency Calculation

["Herb Falk <herb () sisconet com>" <Herb () sisconet com>]

I am creating a dissector that needs to be able to calculate the transmission latency of a packet.

The protocol being dissected has the timestamp of the "transmission", I need to be able to gain access to the time of 
capture of wireshark in order to calculate the difference.  Anybody know an example/documentation pointer?

Thanks in advance.
