 * NAME
 *   36. dataTypeTimestamp4.js
 *
 * DESCRIPTION
 *    Testing Oracle data type support - TIMESTAMP (4) WITH TIME ZONE.
 *
 * NOTE
 *   TIMESTAMP support is still under enhancement request. This test is suspended.
 *
 * NUMBERING RULE
 *   Test numbers follow this numbering rule:
 *     1  - 20  are reserved for basic functional tests
 *     21 - 50  are reserved for data type supporting tests
 *     51 onwards are for other tests
