No.  That just set's ProDOS's internal representation of the time.  It
doesn't affect the clock card at all.

In fact, Copy II+ only provides that option if there is no clock installed
in the machine (it tests the "clock present" flag in the ProDOS global
page machine identification byte, which is set at boot time if on a
IIgs or a Thunderclock is installed; a driver loaded later for an
incompatible clock should set this bit, as my one does).


ProDOS doesn't provide any way to set the clock - the built-in driver
only reads the time.  You need a separate program to set the clock,
and a different one is required for each brand of clock card (including
chip-based clocks, such as the AppleWatch and No Slot Clock).
