0 - 2 of 2 tags for century

I am using a multiload to insert and update rows in a table. The date on the input file is formatted as dd-mmm-yy, when I insert it into the table using
 
:date_field (DATE, FORMAT 'DD-MMM-YY')
after the insert is complete, the date is stored as 7/25/1913
How can I get the century to be 20?
 

My data:
15-MAR-11 07.54.08.000000 AM
15-MAR-11 07.53.40.000000 AM
15-MAR-11 07.53.04.000000 AM
15-MAR-11 07.52.55.000000 AM
15-MAR-11 07.52.16.000000 AM

My current DDL:
CREATE multiset TABLE dbname.dbtable
(
CREATE_DATE timestamp(6)
);

My current TPT Insert statement:
'INSERT INTO '||@TargetDatabase||'.dbtable
(
CREATE_DATE = :CREATE_DATE (TIMESTAMP, FORMAT ''DD-MMM-YYBHH.MI.SS.S(6)BT'')
);'

The data is being stored in the database table with century of '19' instead of '20'. My data will always be century of '20':

CREATE_DATE
1911-03-15 07:54:08
