pgadmin sql server migration timestamps

Hello,

I'm trying to migrate a sql server db to a postgresql db using pgadmin 1.2.0
migration plugin. When doing that I obtain this error :

Creating table: AHEPATCH
  Copying data...

An error occured at: 15/02/2002 9.46.58:
-2147467259: Error while executing the query;
ERROR:  Bad timestamp external representation '2001-12-04 00.00.00'


the field that causes the error is :

PTDATINS    datetime    8

in AHEPATCH. In this column I have this date : '04/12/2001'. I don't know
which is the problem, can you help me ?

    Samuele.
