How many GPS owners happen to have $30,000 GPS simulators to check
their $300 GPS/NTP servers?  Some of mine did, most did not.

Seems to me the negligence is in the GPS manufacturer that failed to
notify their customers.

To be fair, Avidyne and Telit did notify their customers, but not with
a fix or enough lead time to swap out the units.
