Log Proxy round-trip response time

[#1]

I need to capture the variable client.sent.end.timestamp in the proxy preflow response. It's a catch 22 situation to capture this timestamp since the response is not sent to the client yet. I am not able to get this variable in Postflow either as only message logging policy can be attached there. Any ideas? Thanks in advance.

Where in the proxy can I get the value of the variable client.sent.end.timestamp given that the response wouldn't have been sent to the client -- the farthest I can go is postflow response flow, which is not the right place.

@Vijay Govind - please refer to this community discussion on the same topic.

I reviewed the other post. I understand it is not possible to get the exact timestamp outside analytics. I hope Apigee extends the capabilities of Post Client flow so that the developers are able to attach and exercise policies other than just Message Logging policy.
