Just wondering w.r.t KoD packets. What does the standard software return
in the various Timestamp fields when it sends a KoD packet?
Perhaps a "known bogus" timestamp could be included in the packet so
that software that ignores the Stratum field of 0 will tend to cause the
software to set itself to a known bad date  .
 Say 2000-10-13 13:13:13 or something. Actually if someone could
write a perl/python script that just returned that date in KoD mode
then it might be easy for server operators to redirect queries from
abusive IPs to that server.
