LinkHut only has playback/output ports and transmits time, right?

If so, simply query the output port's latency-range and use the max.
Then offset the timestamp to transmit by the output's latency  (send
future time so that by the time it arrives on the physical outputs a bit
later it's valid).

You may want to subscribe to jack's graph-order callback and update the
alignment when connections change..
