It became:
    public void beforeCreate() {
        setMutateInfo();
        dateCreated    = new Date();
        userIDCreation = SecurityUtil.getCurrentUser();
    }

    public void beforeUpdate() {
        setMutateInfo();
        timeMutated    = new Timestamp(new Date().getTime());
        userIDMutation = SecurityUtil.getCurrentUser();
    }

setMutateInfo does things that are needed for beforeCreate and
bedoreUpdate. It is of-course private void.
