Check timestamps on Talon SRX position reports?

Is it possible to use CANJNI.FRCNetCommCANSessionMuxReceiveMessage to see when the last quadrature position report came in from a Talon SRX? We’re trying to figure out how steadily they come in.

We have some code that we use to detect what’s on the CAN bus that appears to extract the timestamp from the last status report from each PDP, PCM, and SRX on teh CAN bus (and which I’ve successfully modified to also check for SPXs), and was wondering if it can be modified to check for specific messages, not just status messages… I just don’t know the specifics of how CANJNI.FRCNetCommCANSessionMuxReceiveMessage works and how to extract the timestamps from messages other than status messages.
