Understanding Appointment attribute

[janrif]

Would it be fair to say that UR's 'Appointment' is related directly to Outlook? Since I don't use Outlook, using it seems like a wasted attribute because reminders & such are tied to Begin Date or Begin Time. So for a non-outlook user like me, it would make more sense to use only Begain date/time to minimize data entry. Do I have this about right?
