All day events with Date module

I have an install of the latest non-dev Date and Calendar modules on D7. If memory serves me correctly, it was possible on D6 to enter a date, leave the start time blank, and have it be an "All Day" event.

For the life of me, I am having problems creating a date field that will do this. If you require the date field and have granularity set to minute, then you are required to also enter a time.

What am I missing to make events All Day??
