Thanks Leo.

For you low level time nerds, yes, even DoD can't get GPS time / UTC / UT1 / leap seconds right the first time. Synchronizing 3 time scales across a leap second discontinuity is really, really hard. More info about ICD rev-J here:

"RFC Title: 2018 Proposed Changes to the Public Documents"

or search for RFC 374 here (page 67/117):
