Salient fact: last representable date is April 6, 2019.

the world (er, GPS epoch) ends a second time in 2019, it already ended once in 1999.

Here's some handwringing from before the first rollover of the GPS epoch: http://www.leapsecond.com/notes/gpswnro.htm

Using the leap second indicator didn't occur to me, but burning in the week of manufacture (or firmware compile date, as ublox apparently does) did.
