Documentation
Interval in minutes at which to display appointment reminders.
Once an appointment becomes due, Emacs displays reminders every
appt-display-interval minutes. You probably want to make
appt-message-warning-time be a multiple of this, so that you get
a final message displayed precisely when the appointment is due.
Note that this variable controls the interval at which
appt-display-message is called. The mode line display (if active)
always updates every minute.
