It is evaluated in WP_http::request() method, which has a helper function, wp_remote_request() in the wp-includes/http.php file.
http_request_timeout accepts a single argument in the form of an integer that specifies the timeout duration in seconds.
Example:
The following example extends the timeout duration from 5 seconds to 30 seconds.
