How to map Timestamp with time zone column?!

[CIJOML]

Hi All,

I am trying map Timestamp with time zone column to ibatis, but without 
success. Database is Postgresql 8.1.4.

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
  PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
  "http://www.ibatis.com/dtd/sql-map-2.dtd";>
<sqlMap namespace="Firma">

<resultMap id="Kontakt" class="Kontakt">
<result property="id_kontakt" column="id_kontakt" />
<result property="id_administrator" column="administrator_id_administrator" />
<result property="id_lokace" column="lokace_id_lokace" />
<result property="unix_time" column="unix_time" />
<result property="zaznam" column="zaznam" />
<result property="poznamka" column="poznamka" />
</resultMap>

   <select id="getKontakt" resultClass="Kontakt">
         SELECT
         ID_KONTAKT as id_kontakt,
         ADMINISTRATOR_ID_ADMINISTRATOR as id_administrator,
         LOKACE_ID_LOKACE as id_lokace,
         UNIX_TIME as unix_time,
         ZAZNAM as zaznam,
         POZNAMKA as poznamka
         FROM Kontakt
         WHERE id_kontakt = #value#
   </select>
<!-- Use company object (JavaBean) properties as parameters for insert. Each 
of the
    parameters in the #hash# symbols is a JavaBeans property. -->
<insert id="insertKontakt" parameterClass="Kontakt">
    <selectKey resultClass="int" keyProperty="id_kontakt">
      SELECT nextval('kontakt_ID_kontakt_seq');
    </selectKey>

      INSERT INTO
      KONTAKT (
      ID_KONTAKT,ADMINISTRATOR_ID_ADMINISTRATOR,LOKACE_ID_LOKACE,
      UNIX_TIME,ZAZNAM,POZNAMKA
      )
      VALUES (
      #id_kontakt#,#id_kontakt#,#id_administrator#,#id_lokace#,
      #unix_time#,#zaznam#,#poznamka#
      ) <!-- PER_ID vlozeno automaticky -->
</insert>
<!-- Use company object (JavaBean) properties as parameters for update. Each 
of the
    parameters in the #hash# symbols is a JavaBeans property. -->
<update id="updateKontakt" parameterClass="Kontakt">
      UPDATE Kontakt
      SET ZAZNAM = #zaznam#
      WHERE ID_KONTAKT = #id_kontakt#
</update>
<!-- Use company object (JavaBean) "id" properties as parameters for delete. 
Each of the
    parameters in the #hash# symbols is a JavaBeans property. -->
<delete id="deleteKontakt" parameterClass="Kontakt">
      DELETE FROM Kontakt
      WHERE ID_KONTAKT = #id_kontakt#
</delete>

</sqlMap>

Well Also Kontakt class is ready with setters and getters and String 
unix_time.

Now I call class:
//KONTAKT
Kontakt newKontakt = new Kontakt();
newKontakt.setId_administrator('3');
newKontakt.setId_lokace('4');
newKontakt.setUnix_time("20006-04-02 18:34 CET");
newKontakt.setZaznam("Prvni zaznam");
newKontakt.setPoznamka("Fakt prvni pokus o poznamku");
sqlMap.insert("insertKontakt", newKontakt);


And error popups:

When I call it manually, I am able insert it:
insert into kontakt values('1','3','4','2006-04-05 15:18 CET','test','test');

How can I see string passed to the postgresql server?
How to fix this mapping?

Thanks a lot for quick help
