You're talking about banner delay Bill, whereas Marc was asking about
the total time that a connection has been open. Short of some
grepping and awking, I can't come up with any way to see that...

ps aux | grep '/usr/sbin/exim' | egrep -v -- 'grep|-Mc' | awk '{print $9}'

With a little massaging you could correlate that time since the
process started to the hostname, but it sounds like a giant kludge
that will be prone to error. I could be misreading it though.
