"The math" is a subtraction between two time stamps for *different* packets, so
not only do requests and responses have to be identified, the request
corresponding to a particular response has to be identified for each response
and the time stamps of the requests need to be saved in a data structure so
that the time stamp of the corresponding request can be found, so more needs to
be done than just "add in a few lines to do the math".

This would be a useful feature, but it's more complicated than just adding a
few lines of code.
