SVN commit 455447 by kainhofe:

For all-day events the DTEND should be set to the last day of the event, 
not to the next day after the event (We misunderstood rfc 2445 in this 
regard). E.g. a DTEND: 20050831 *does* occur on August 31 (and end on that 
date). Originally, we also had it that way, but then misunderstood the rfc 
and for kde 3.1 we used the next day after the event as DTEND. Evolution 
and Mozilla do it similarly, but it's wrong, nonetheless. Actually, after 
pointing out the problem to them, the evolution guys will also use the 
correct way.

See http://www.imc.org/ietf-calendar/archive1/msg03648.html (written by 
one of the authors of rfc 2445, so that's kind of authoritative)
