What you’re describing is the easy part - obtaining the start time is relatively straightforward (it would depend on the source), and putting the time in the container is also easy (depends on the sink), the trick is wiring the two together in the “right” way.

Do I attach this start time to each buffer as metadata, or should I place a message on a bus?
