[Inf-IT DAVcl] All day event considered as from midnight to midnight

Hi "list", When I tick the "All day" check box for an event, it is actually created as during from 0:00 to 0:00. Here is part of the ics file : BEGIN:VEVENT SUMMARY:Test [...] DTSTART;TZID=Europe/Paris:20130712T000000 DTEND;TZID=Europe/Paris:20130712T000000 END:VEVENT Is there a place where I can change this behavior ?
