I support several PHPNuke sites and the page preparation time is measured by taking a microtime stamp at the very beginning of the script and another just before echoing the last couple of lines at the bottom of the page and producing something like the following on the bottom of the page;
Page Generation: 0.376 Seconds
This does not measure all the elements of delay, however, which can be broken down into the following;
1. Time it takes for browser to get the request packet to the web server. 2. Time it take the web server to begin processing the request. 3. Time it takes to load PHP and for PHP to load your script (CGI or MOD?)
4. Time it takes for your script to complete execution is measured above.
5. Time it takes for the cached output from your script to be delivered back to the browser. 6. Time it takes to perform 1-5 above for any imbedded images, etc requests. 7. Time it takes for the browser to render the completed page.
It's not clear from your question, which of these you wanted to measure. If you were to develop another application running on your local machine, then you could use things like socket connections to simulate a browser, invoke the page and measure the total span of time. In this case I would recommend using CURL, or Pears HTTP_REQUEST instead of dealing with the intricacies of building the request, etc.
Hope this helps,

try timing the fsockopen() or (whatever you use) call. :) That'll give you a reasonable estimate.
