SoapEncUnitTestCase - Incorrect Timezone Handling
-------------------------------------------------

                 Key: JBXB-142
                 URL: http://jira.jboss.com/jira/browse/JBXB-142
             Project: JBoss XML Binding (JBossXB)
          Issue Type: Bug
    Affects Versions: JBossXB-1.0.0.SP2, JBossXB-2.0.0.CR9
            Reporter: Darran Lofthouse
         Assigned To: Darran Lofthouse
             Fix For: JBossXB-2.0.0.CR10, JBossXB-1.0.0.SP3


The testcase SoapEncUnitTestCase uses incorrect timezone handling.

The following code is within the instantiation of the object being marshalled: -

         Calendar varDateTime = (Calendar)new GregorianCalendar(96, 5, 1);
         int offset = varDateTime.get(Calendar.ZONE_OFFSET) + varDateTime.get(Calendar.DST_OFFSET);
         StringBuffer buf = new StringBuffer();
         buf.append("GMT");
         if(offset > 0)
         {
            buf.append('+');
         }
         buf.append(offset);
         varDateTime.setTimeZone(TimeZone.getTimeZone(buf.toString()));
         struct.setVarDateTime(varDateTime);

1 - The year is 96 not 1996 so this is before DST offsets began.
2 - The two gets return an offset in milliseconds but the code assumes it is in hours.
3 - The TimeZone.getTimeZone is being passed a "GMT+3600000" this is not understood so GMT is returned by default.

When this test case is executed in CEST the setTimeZone changes the time to: -

<varDateTime>0096-05-31T23:00:00.000Z</varDateTime>

This is expected in the resulting XML.

For portability the Calendar instances needs to be constructed in a way to avoid the users timezone affecting the outcome i.e. varDateTime should be constructed have the timezone set to GMT and then set the exact time.
