I am often amused by online complaints that someone's handheld GPS
has the time wrong by two seconds. I surmise that with such units
it is also the case that the position it gives is correct for
where it was two seconds ago.

One thing that is clear from Levine's article is that you get what you
pay for, and that if you really want it done well you have to pay lots.

What I don't understand is why this does not generalize to leap seconds.
