Subject: [quicwg/base-drafts] "retransmitting" old timestamps in ACK frames (#308)

We need to include advice on the creation of ACK frames when an ACK frame was lost.  The advice from @ianswett is that new timing information isn't valuable.  Both endpoints only need to maintain timing information for individual packets for a short period, so retransmission of old timing information isn't valuable.

Thus, we should recommend that endpoints do just that: maintain a short list of packets that they want to provide timing for.  They should then not worry about re-sending any timestamps from lost packets.
