The documentation at http://nginx.org/r/proxy_read_timeout suggests "yes".

A quick test indicates that it does:

In one shell, a listener that will be slow to respond:

  nc -l 127.0.0.1:10880

nginx.conf:

  server {
    location / {
      proxy_read_timeout 6;
      proxy_pass http://127.0.0.1:10880;
    }
  }

Test command:

  date; curl -v http://127.0.0.1/test; date

I get a http response after 6 seconds.

"Gateway Timeout" is 504.
