If I leave it out of the qualifier construct, I have no problems. Any idea why this is wrong? endDate is an NSTimestamp mapped to DateTime column.

Maybe the class cast exception occurs because endDate is a NSTimestamp, not a NSKeyValueCoding.Null. I've never used NSKeyValueCoding.NullValue to signify null in a qualifier. Have you tried "null" instead?
