DataDeploy: Automatic timestamp field...

I am deploying metadata from TeamSite into an Oracle 9i database. Everything is working fine, however, the application team would like a column added to the table that is a timestamp column. Whenever a record is inserted or updated the timestamp in this field should be updated to the current time. Is there a known way to do this in DataDeploy or do I have to do this in Oracle and DataDeploy won't know anything about this?
