While $request_time is indeed accounts for complete request time
when used in logs, it can be accessed (and saved) at some
intermediate point. E.g., by using something like
set $header_time $request_time;
one may save time since 1st bytes were read from a client till
rewrite rule processing. This is basically identical to "time
necessary to read all the packets of a particular HTTP query" that
was asked (at least as long you don't try to count reading a
request body).
