[erlang-questions] signal arrival time

[Joe Armstrong]

Yes - read the manual pages for the BIF erlang:trace.  You basically
set up a trace process
that watches the process you are interested in, then you ask the
system to send you timestamp
information for each message that is received.

This is described at http://www.erlang.org/doc/man/erlang.html#trace-3

Alternatively you could you fold something like this into your code:


      loop() ->
            receive
                 {ts, Time, Pattern1} ->
                        ...
                 {ts, Time, Pattern2} ->
                        ...
                 Any ->
                        self() ! {ts, erlang:now(), Any},
                        loop()
             end.
