[time-nuts] NAVSTAR proteus GPS time and frequency unit

[Chuck Harris]

Seems to me that there is more to this than just
getting the displayed date wrong.

It is true that the date will present wrongly, but
what about leap seconds?

If the GPS week rolls over at 1024, how will the
GPS figure out which is the proper calendar date
to apply the leap second?
