carriesSenderClock property
Whether this transport already puts the sender's clock on the wire.
LSL does: every sample carries the sending machine's lsl_local_clock()
reading, which is what MessageTiming.sourceClock reports. Transports that
return false get a PeerClock reading stamped into the message envelope by
the layer above, so a receiver has something to compare against — but a
transport that has its own, better sender clock must say so, or the two
stamps disagree and the weaker one wins.
Implementation
bool get carriesSenderClock => false;
