dbtimestamp: An extension of TimestampType which maps to the database's current timestamp, rather than the jvm's current timestamp.

Note: May/may-not cause issues on dialects which do not properly support a true notion of timestamp (Oracle < 8, for example, where only its DATE datatype is supported). Depends on the frequency of DML operations...
