DESCRIPTION

Pass a pointer to a double to receive the time, in seconds, it took from the start until the first byte is received by libcurl. This includes CURLINFO_PRETRANSFER_TIME(3) and also the time the server needs to calculate the result.

When a redirect is followed, the time from each request is added together.
