Wrong display/update of TIMESTAMP WITH TIMEZONE data in diect mode

Wrong display/update of TIMESTAMP WITH TIMEZONE data in diect mode

For demo, PLS create a table

CREATE TABLE TS_TEST
(
  ID NUMBER (9,0) NOT NULL,
  TS TIMESTAMP(6),
  TS_TZ TIMESTAMP(6) WITH TIME ZONE,
  TS_L_TZ TIMESTAMP(6) WITH LOCAL TIME ZONE
);

ALTER TABLE TS_TEST ADD
(
  CONSTRAINT "_PK"
  PRIMARY KEY
  (
    ID
  )
);

And insert a sample record

INSERT INTO TS_TEST (
  ID, TS, TS_TZ, TS_L_TZ)
VALUES (
  /* ID      */  1,
  /* TS      */  TIMESTAMP '2020-01-01 12:30:00.00 Israel',
  /* TS_TZ   */  TIMESTAMP '2020-01-01 12:30:00.00 Israel',
  /* TS_L_TZ */  TIMESTAMP '2020-01-01 12:30:00.00 Israel'
);

Now build a small app and show the data using TSmartQuery in a data grid.

If you connect with Oracle client, data is displayed correctly:
  1. 1
  2. 01.01.2020 12:30:00,000000
  3. 01.01.2020 12:30:00,000000 ISRAEL
  4. 01.01.2020 12:30:00,000000
when connected with direct TCP/IP, TIMESTAMP WITH TIMEZONE is wrong:
  1. 1
  2. 01.01.2020 12:30:00,000000
  3. 01.01.2020 14:30:00,000000 +02:00   // two hours later !!
  4. 01.01.2020 12:30:00,000000
If you update the column, it gets worse. Result displays like that
  1. 04.01.2020 06:30:00,000000 +66:00
Furthermore, i do not get the TZR dislayed as ISRAEL.

PLS help.
