Not at all! The EventMedia bubble in the LOD cloud used to contain many 
upcoming events (which will be past events at some point in the future ;-)

I agree that OWL Time should be revised at some point, but hey, we just 
have one blank node !
(made up) Example of a description of a past Radiohead concert in LA:

<http://data.linkedevents.org/event/1380633>
   a lode:Event;
   dc:title "Radiohead: Haiti Relief Concert";
   lode:involvedAgent <http://data.linkedevents.org/agent/14055285>;
   lode:atPlace <http://data.linkedevents.org/location/8943964>;
   lode:inSpace
     [ wgs84:lat "34.101624"^^xsd:string;
       wgs84:long "-118.32331"^^xsd:string
     ];
   lode:atTime
     [ time:inXSDDateTime "2010-01-24T20:00:00"^^xsd:dateTime ];
   owl:sameAs 
<http://www.last.fm/event/1380633+Radiohead%3A+Haiti+Relief+Concert>;
   owl:sameAs <http://www.last.fm/event/1380633/>;
   dc:publisher <http://www.last.fm>.

There are extensions for this, either using the patterns from the F 
event model or with direct properties. It would be better to start from 
this rather than re-inventing what already exists.
Best regards.
