When you make a new post request, a timer starts and keeps going until response
Fiddler already maintains timers for every request. You can see them by selecting the session in the Web Sessions list and looking at the Statistics tab.
The FiddlerBeginRequest timer marks the start of the sending of the request.
The ServerBeginResponse timer marks the first byte of the server's response.
