Adding a Zone Field to the SDP Session Structure
int sdp_add_zone(sdp_session_t *session, uint64_t time, const char *offset);
The sdp_add_zone()
function adds the ZONE (z=) SDP field to the session structure that is specified by the
value of the session parameter (sdp_session_t)
using the time and offset parameters.
You can add multiple time and offset values for a single zone field by calling
this function for each time/offset value pair.

sdp_add_zone(3COMMPUTIL) man page.
