Why not sending a syncronized custom event and use libdataprotocol for the
udpsink/src. if you want to see the actual time&date on the sink, you can use a
pad_probe and configure textoverlay with the message (or make a copy of
textoverlay that does handles the message).

That brings me to the point that it would sometimes be useful to have an element
config event that carries the element name and property value pairs. when an
elemnt receives it, its sets its properties to those values.
