It takes more than a simple patch, but the date bug can be completely
squashed by simply storing the timezone in the in memory register.  It could be
as compact as a time_t plus a 1 byte index into a timezone table.  All
register dates are displayed (and all scheduling done) relative to the
associated timezone, not the system timezone.  This preserves the date, *and*
the time of day across any changes to the system timezone, and is guaranteed
not to break old versions (any more than they were already broken) or book
closing code.

It might not even be that bad a change to the register.  Add the tz field
to the in memory data, and a tweak to the date display code.
