Yes, you are quite right that XMLSchema data types could be used with the current version of DAML-S/OWL-S. The current version mentions time only in the most trivial way. But Time.daml has been kept around because there are plans to make more interesting statements about time, which would require the use of an ontology. It is my hope that some additional work will be done on this sometime this year, and it will be based on the OWL Time ontology being developed by Jerry Hobbs and others. So the simple Time.daml file currently on the DAML-S/OWL-S release is really just a placeholder.

Sorry for the confusion; we should have caught that.
