Hi!
IMHO, its quite easy. Just add additional node into ETD where
sending e*Way will put timestamp before publishing this into IQ.
And at the "end"-e*Way compare current time with the time
in your node. Of course, time should be synchronised on both (starting and ending) hosts.
AFAIK, there are no such functionality in e*gate (at least in e*Gate 4.1.2)
