 From the human perspective I'm not sure.

I suspect the general way of thinking is along the lines of

"I want a meeting every thursday at 14:00 starting next week."

Why should the UI force a user into figuring out the date and time of 
the first instance? What if DST starts that weekend?

Data models should be very encompassing and unambiguous. UIs are the 
translation between the messy human perceptions and the exact world we 
developers live in.
