Yes you can.

You can trace the process you want to observe (use the flags 'r' for
receive and 'timestamp' for attaching the time to it) and then receive
the trace messages using your own trace event handler. I would also
recommend that you use matchspecifications in case you are only
interested if 1 specific message has arrived, it is much more

I wrote a pretty straightforward tutorial on how to do these sort of
things in one of the EUC a couple of years ago. You can find it here:
