I dunno about ZPublisher, but ZServer uses its DebugLogger to
log at 4 times: receipt of request, all data received, response 
returned from zope, all data sent back to client.
Maybe you could monkeypatch DebugLogger to take the time of handoff to Zope 
(the 'I' line logged in continue_request) and insert it as a variable
in the HTTPRequest, which you could then read and use to print
your message from application code.
Dunno how to meet your goal of tracking time across a redirect...
unless maybe the redirect has a timestamp in the
query string.
