Hi TJ,
With the CSS there is no command that you can use to log client requests with timestamps, the closest command we have are:
-show service summary- which will give a snapshot of the connections that each service is working on.
-show summary- displays a historical record of connections that each content/service has received.
-show flows- Well you already know this command and that it does not have timestamps.
So the answer will be no, unfortunately the CSS does not have this kind of features, at least not now.
Regards.
Josega.
