DNP3 Dissector does not decode the 6-byte Time Stamp component of Application
Layer Object 50 Variation 3 (Last Recorded Date and Time). The object had
previously been defined in the dissector but was never referenced when actually
decoding the packets so any existing instances of this object will produce an
"unknown data chunk" section where the time stamp should be present.
I have attached both a capture file that exhibits the problem (See packet #11)
as well as a diff/patch that will correct the issue.
Contact me if there are any questions,
Chris Bontje
