+         * time.<br>

+         * This test completes normally if this constant is changed to true.
+         * Probably this test was designed for this mode. But with
+         * STORE_LOCAL_TIME = false this test is useless. On Java 10 only 57% of
+         * conversions tested by this test are successful, the remaining 43%
+         * have different offsets due to differences in DST transitions between
+         * timezones.
