Create an all-day Google Calendar appointment?

Is there a way to create an all-day appointment with Google Calendar?

Only “Create Event” can be selected in the action dropdown menu, but the start and (optionally) end must be specified there. Even if the end is left blank, a start time must be specified. But there is no option to create an all-day event.

No time can be selected at all via the “Create Quick Event” action. I already checked on that.
