No, you need to update it regardless.  The date is computed by

I think it depends more on the clock driver being used in ProDOS.  The
Thunderclock driver built into ProDOS, which I believe most clock
cards operated like, has to compute the year but the IIgs clock driver
does not.  I haven't used an 8 bit Apple II with a clock card in quite
some time but I know I've never had to patch ProDOS on my IIgs.

Yes, that's true--the clock driver is the relevant part of ProDOS.

But the OP asked about a Timemaster II HO, which would use the
ProDOS ThunderClock driver with the year table.

It's too bad that Apple "standardized" the ThunderClock, with its
missing year digits, but since they did so, most other clocks
arrange to look like ThunderClocks to ProDOS.

Built-in ProDOS support for the IIgs clock was a nice improvement,
but it was too different and too late for the 8-bit Apple II world.
