Description for the result (QU_RESULT.DESCRIPTION) is incorrect for TIMESTAMP data types (4333540)

The code generated by Quest Code Tester For Oracle is wrong for TIMESTAMP data types.
The description for the result (QU_RESULT.DESCRIPTION) is incorrect for TIMESTAMP data types.

For DATE data types the following is generated (correct):

FUNCTION fp_to_string (value_in IN DATE)
    RETURN VARCHAR2
IS
    l_string     VARCHAR2 (32767);
BEGIN
    l_string     :=
          CASE
                WHEN value_in IS NULL THEN 'NULL'
                ELSE TO_CHAR (value_in, 'YYYY-MM-DD HH24:MI:SS')
          END;
    RETURN l_string;
END fp_to_string;

For TIMESTAMP however, the following is generated, which is incorrect:

FUNCTION fp_to_string (value_in IN TIMESTAMP)
    RETURN VARCHAR2
IS
    l_string     VARCHAR2 (32767);
BEGIN
    l_string     :=
          CASE
                WHEN value_in IS NULL THEN 'NULL'
                ELSE TO_CHAR (value_in)
          END;
    RETURN l_string;
END fp_to_string;

No specif format mask is used in the call to TO_CHAR.  
The same holds for EXP_TO_STRING.

Note: To reproduce the error create a simple test with one function that returns a date, and another  test  that returns a timestamp.  Then generate the code with Quest Code Tester for Oracle
