Dave, this is a case where the rules are totally wrong. TTL here is a
HOP count and not a time-to-live, in spite of the label. In IPv6 it's
really called a hop count rather than ttl but we should not propogate
this error. I can't find anything either in the NTPv4 Draft RFC or RFC
1305 so I don't know what RFC you mean. Can you clarify? Multicast
doesn't work the way that it was originally designed. It also make no
sense to specify a value other than what you want the ttl be set to.
