Floating events

Graham Gough got in contact to say that Data::ICal::DateTime was barfing on an export of his Palm pilot calendar to .ics and saying

    Couldn't find end *or* duration:                                                  
    BEGIN:VEVENT                                                                      
    DESCRIPTION:Check 2341 assessment\n##F@@@@@@@@@@@@@@@@\n                          
    DTSTAMP:20051003T080457Z                                                          
    DTSTART;VALUE=DATE:20051003                                                       
    SUMMARY:Check 2341 assessment                                                     
    UID:palm-datebook-007f9a18-000076ef-Graham Gough@rpc204                           
    END:VEVENT        

Which is right because there's no DTEND. Except it turns out the evnt was a floating event - as per section 6.2 of rfc2445 - recommended practices :

    A calendar entry with a "DTSTART" property but no "DTEND"
    property does not take up any time. It is intended to represent
    an event that is associated with a given calendar date and time
    of day, such as an anniversary. Since the event does not take up
    any time, it MUST NOT be used to record busy time no matter what
    the value for the "TRANSP" property.

At first I did some sort of horrific hack that turned a floating event into an 'all day' event but that was, well, bogus. When I got back $business trip abroad I ripped it out and did the sensible, cleaner, correct option of having a floating() method and getting rid of the requirement to have a DTSTART and either a DURATION or DTEND.
