Is it possible to log in NGINX the time of a request from a client?

Question

Nginx

Those. not the time of the request on the server itself or upstream, but:
the time (DNS + Connect + TLS + Wait + Receive) from the creation of the request to its end.
It sounds crazy but: maybe some kind of headers can really be thrown?

It is completely impossible to record the time of the first request and the last, because it is not clear where the last one is.
