Clarification on what timestamp to use on a retransmitted packet

[kierank]

It's semi-obvious that it must be the original packet transmission timestamp but this needs to be made clear.

It is worth mentioning that the use of the packet sending time to stamp the packets is inappropriate for the TSBPD feature, since a new time (current sending time) is used for retransmitted packets, putting them out of order when inserted at their proper place in the stream.

This sentence is not at all clear. libsrt uses the original timestamp as one would expect for a retransmission.

Timestamping rules are to be changed in SRT v1.6.0. Only origin packet time will be used in both live (TSBPD on) and file modes (TSBPD off).
