If I add a event that is, for example, starting tomorrow at 9am and ending at 11am at the same day, the generated iCal-File says:
DTSTART;TZID=Europe/London:20120316T090000Z DTEND;TZID=Europe/London:20120317T110000Z
So it's too long, one day, all the time ...
Board 3.2.3, Calendar 3.2.2
Edit: I have solved the problem by adding the "event_all_day"-switch at the else if - section after line 351 @ icalendar.php
