> 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.
