Hence the stress on "should". :-}

The description of how templates work is based on the assumption that
within every definition, there's a set of possible statements that are
perpendicular to / independent of each other and that every one of these
is individually either inherited as-is from the template, expanded
(additive inheritance) from the template, or overwritten outright. This
does not hold for timeperiods, as, e.g., "December 6th" and "first
Tuesday in December" may or may not refer to the same day. I wouldn't
dare predict how the current code, much less the future code after
fixing the abovementioned bug, does/will/should handle such cases.

Having that said, I *would* expect "use AllButTuesdays" to *add* the
time intervals of AllButTuesdays to the timeperiod, rather than
*substracting* them like "exclude AllButTuesdays" should.

Kind regards,
