Don't be scared of Y2K problem itself, but avoid those who try to test
it... Interesting, what issue does INTERNIC plan to test - DNS (what's
wrong with DNS at all? In theory there is not ANY place whene DNS server
or resolver can be sencitive to the YEAR at all), or their crazy billing
system (it can be sensitive, but why do they need NTP).
