One particular piece of crapware of the tucows archive variety would retry once per second if it hadn't heard a response - but a ICMP Port Unreachable would trigger an *immediate* query, so it would basically re-query at whatever the RTT for the path was.
I've said in other forums the only solution for this sort of software is to return the wrong time (by several months). The owner might actually notice then and fix the problem. Just not returning anything means the time still works on the querying device (especially if it uses multiple servers) and the problem will not be noticed and it will continue. -- Simon J.
