Yes: PhantomJS has an onResourceReceived callback which fires every time
a chunk of a resource on the page is received. It take one argument
which is an object containing, amongst other things a timestamp.

Poltergeist also exposed this data. You can access it by calling
"page.driver.network_traffic".

YMMV etc, but maybe this helps.
