Sure, the seconds are still lapsed seconds since (weekly) epoch . . .

(Not to mention the post corrections broadcast upwards from the ground to adjust for relativistic time drag between Earth surface nominal 1G and sat orbit height gravity)

Point being, many timing applications use lapsed time since X counters and are part of systems designed to handle rollover.

The mindset of just adding more bits to a counter or recording more decimal points isn't always appropriate or the 'best' fix.

That's just the General Relativity correction. There's also a Special Relativity correction to account for time dilation caused by the satellite's speed, which works in the opposite direction to the GR correction yet the two don't exactly cancel each other. Plus there are some others (Doppler shift, Sagnac effect, etc.)
