cheap GPS

It's too early to say with high confidence, but you had to stretch pretty
far away from the question you asked (will it cause time problems with
NTP, etc) to find a problem with the GPS rollover. General reports are
that it went better than expected and that few critical systems were
impacted. If you had asked whether anyone would be hit by the rollover, I
would have said of course there were going to be systems and people hit.
It may be fun to watch the PR wars that result.

I carefully avoided asking about NTP or any specific uses of the time
signals. My question was would the GPS rollover cause more or fewer
problems than when NIST set daylight savings time wrong in 1992.
Approximately 600 people have reported problems, so far, due to the GPS
rollover. NIST claimed fewer than a dozen reported problems when daylight
savings time was set incorrectly in 1992.

Both are pretty small numbers, but as you point out people aren't very
good at understanding extremely rare risks. You need to be carefull when
you say XYZ will cause almost no problems, you didn't mean they specifically
wouldn't have a problem with XYZ. See airplane crash, nuclear plant
meltdown, etc. It is a PR problem, and technical people aren't always
the best ones at explaining how a risk affects the public.

Sean,

this is silly. If you compare the number of GPS receivers in the world and
the number of WWVB receivers, there should have been hundreds of thousands
to millions of complaints to have similar ratio. You forgot to compare it
to a MAE-East outage, current solar activity or hurricane Bret. Last time
I looked, nanog still had something to do with network engineering and
little to do with automotive navigation, surveying, or any of the other
GPS applications.

In the timing world, which is the only thing that WWVB could impact, the
reports of major problems are not showing up.
