DT_DBTIMESTAMP [Result] 
Changes the time value represented by the DT_DBTIMESTAMPOFFSET data type to UTC. If a value represented by the DT_DBTIMESTAMPOFFSET data type overflows the range of the DT_DBTIMESTAMP data type, the DB_E_DATAOVERFLOW error is returned. Removes the fractional second value when its scale is greater than the number of fractional second digits that the DT_DBTIMESTAMP data type can contain. After removing the fractional second value, generates a report about this data truncation. For more information, see Error Handling in Data.
