For completeness:

http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-dm.html#term-Generation states:

time: an optional "generation time" (t), the time at which the entity was completely created;

and
  wasGeneratedBy(e,-,2001-10-26T21:32:52)


http://www.w3.org/2011/prov/wiki/ProvRDF#Generation
currently shows:

:e prov:qualifiedGeneration [ 
   prov:atTime "2012-04-20T12:29:41-04:00"^^xsd:dateTime;
] .


and I added generatedAtTime and invalidatedAtTime to the OWL.

http://dvcs.w3.org/hg/prov/rev/87c5a3290a53

So PROV-O is caught up with this issue.
