TimeZone.getDefault is wrong if the System TimeZone is set to Rangoon

Question

Hi,
Once the System TimeZone is set to Rangoon i.e (+6:30), TimeZone.getDefault returns a wrong timezone and corresponding timezone offset.
The code snippet with its output is given below.
Code is as below:
System.out.println("The default TimeZone is "+TimeZone.getDefault());
System.out.println("The TimeZoneOffset is "+(TimeZone.getDefault().getRawOffset())/(1000*60)+" minutes");
System.out.println(System.getProperty("user.timezone"));
Output:
The default TimeZone is java.util.SimpleTimeZone[id=Asia/Calcutta,offset=19800000,dstSavings=3600000,useDaylight=false,startYear=0,startMode=0,startMonth=0,startDay=0,startDayOfWeek=0,startTime=0,startTimeMode=0,endMode=0,endMonth=0,endDay=0,endDayOfWeek=0,endTime=0,endTimeMode=0]
The TimeZoneOffset is 330 minutes
Asia/Calcutta.
It would be great if somebody knows what exactly is going wrong. Pls help
Thank You

It looks like a bug in Java that was fixed in 1.4 sometime.
I tried your test using Windows XP and Java 1.4.2. I selected "Rangoon (+6:30)" as my time zone on the Windows Date and Time properties.
The output I got was:
The default TimeZone is sun.util.calendar.ZoneInfo[id="Asia/Rangoon",offset=2340
0000,dstSavings=0,useDaylight=false,transitions=5,lastRule=null]
The TimeZoneOffset is 390 minutes
Asia/RangoonI tried with JDK 1.3.1_09 and found it to behave erroneously (interpreted time zone as Asia/Calcutta).
