You'll definitely want to use the Thunderclock. The Mountain clock has to have
a driver installed in ProDOS 8 while the Thunderclock is the "official" clock
and as such needs no driver added on. Since the Thunderclock doesn't return
the year, you need to use Apple's patcher program to update the year table
which ProDOS 8 uses to calculate the year.

I have an AI Applied Time II clock myself, which is Thunderclock compatible.
On it you can do a PR# to the card's slot to get a menu to set the time. That
might not be a normal Thunderclock feature though. I'd see if anyone has
some software for it if the PR# trick doesn't work.
