Sleep mode does not save milliseconds

Question

I save the object in sleep mode with creation date       

    @Id
    @Column (name = "dtcreation")
    @Type (type = "timestamp")
    private Date creation;

and I put a new date in this field:   

    entity.setCreation (new Date ());
    entityDao.persist (entity);

but when it is stored on db, the time does not contain milliseconds, but put it to 0 if I try to update the value of milliseconds with the request, it works ... can someone help me?

after the persist method, I have a record from 06/01/2011 15: 00: 00.0 but if I did UPDATE, I can change the milliseconds, so db supports it. the database is informix
