Solution Description:

This is usually caused when some change has been made to the
initialisation parameter FIXED_DATE or the system date. It can occur
Under different circumstances.

1. When doing Date testing and the init.ora parameter FIXED_DATE
   has been set to a future date. When the database is started, then
   that date & TIME does not change.

So any objects created will have exactly the same Date & Time
stamp as the FIXED_DATE.

Now When you come to run the EXPORT, it checks the SYSDATE
and the creation dates for the objects.

You need to modify the TIME in the FIXED_DATE parameter,
i.e. add 1 hour or few minutes, etc and you will not
encounter the error ORA-1466 anymore.

1. The Operating System was reinstalled because of the server crash.
   The system date was not set correctly. The year was set to 2001
   instead of 1997 when they reinstalled Oracle. After some DB
   activity
   they realized the date was incorrect and reset it to 1997 causing
   some
   objects to exist with future dates.

Perform full database export without specifying consistent=y and
recreate the database.
