[erlang-questions] signal arrival time

[Kenneth Lundin]

Note that the trace mechanisms should not be used as a regular part of
production code. Trace is intended for trouble shooting and profiling, if
used as part of the regular system it will destroy the possibility to use
trace for trouble shooting alternatively trouble shooting will destroy the
running system.

It would be interesting to know what you are going to use the information
about when a message arrived to a mailbox for? Maybe there are other ways
of solving  your problem?
