I'm working with Fiddler Web Debugger tool version 4.4.4.8.

I've made a request to e.g. www.google.com and fiddler shows that a request is sent and the response is received.

How could I know about and display when the request was sent and when the response is received? start/end dates are not in the left columns in Fiddler.

Is there any setting?

I saw there are some Timers: http://fiddler.wikidot.com/timers

How to display/use them?

Your simplest approach would be to right-click the Web Sessions list's column headers and choose Customize Columns... from the menu.

From the Collection dropdown, choose the Session Timers option and then select the timer of interest in the Timer Name dropdown.

If you just need to profile a single request, you can view the Statistics tab on the right, when clicking on a request in the requests pane like this.

If you need to profile multiple requests, select multiple requests from the left capture pane and you'll see the aggregate performance under statistics tab.

You can also add the Overall_Elapsed column.

For Fiddler 4.6.2, Right Click on any of the Column Headers on the Sessions pane.

Customize Columns > Collection > SessionTimers > ClientBeginRequest and ClientDoneRequest

It appears like this.

Wouldn't ServerBeginRequest and ServerDoneResponse be the columns to use?
@Hutch I suppose that would depend whether you're interested in server performance vs user experience

Pick new new column and go as per the screenshot below and you are done in new Column.
