Well since dates and times without timezones make more sense than datetimes perhaps they don't feel it adds value. Or perhaps they only added xsd:datetimestamp because of OWL 2 and OWL 2 doesn't support date or time and so wouldn't care what XSD did about those :-) Dave -- Hewlett-Packard Limited Registered Office: Cain Road, Bracknell, Berks RG12 1HN Registered No: 690597 England
