A read-create enumeration that, when the schedule's recurrence is set to yearly, specifies which month the scheduled action occurs in; for other recurrence types, it instead indicates how frequently the timer runs. This object's meaning changes depending on timerCtrlSchdlRecurring, so an admin must interpret its value in the context of the recurrence type configured for that same schedule entry. For a yearly schedule, setting this to december(11) would make the action occur every December.
