Introcuding a new timestamp for curl_easy_getinfo():

Browse Source 
CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
handshake/connection is completed (typically SSL, TLS or SSH). By using this
you can figure out the application layer's own connect time. You can extract
the time stamp using curl's -w option and the new variable named
'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.

and negotiations that are specific to the particular protocol(s) involved.

\fICURLINFO_STARTTRANSFER_TIME\fP. The time it took from the start until the

.IP REDIRECT
\fICURLINFO_REDIRECT_TIME\fP. The time it took for all redirection steps
include name lookup, connect, pretransfer and transfer before final
transaction was started. So, this is zero if no redirection took place.
