Hyunsik Choi commented on TAJO-2186:
------------------------------------
Please see some part of testDateTimeType test
{code:title=TestResultSet.java|lineNumber=123}
// assert with timezone
// Current timezone + 1 hour
TimeZone tz = TimeZone.getDefault();
tz.setRawOffset(tz.getRawOffset() + (int) TimeUnit.HOURS.toMillis(1));
Calendar cal = Calendar.getInstance(tz);
assertEquals(tz.getRawOffset(), cal.getTimeZone().getRawOffset());
assertEquals(Time.valueOf("23:00:00"), res.getTime(1, cal)); // <------
Here
{code}
See the last line. A Time object contains a calander object, and the calanedar
object is used for equals(). {{Time.valueOf()}} internally uses
Timezone.getDefault(), but {{res.getTime()}} uses a timezone derived from a
given calendar object. That's why it causes this failure in some timezone.
