Wrong time when using java Calender

Question

Hi All,
I have a Solaris 9 system. The Timezone for which is set to "TZ=Asia/Colombo". I have written a small java code to get the time using Calender class.
The problem is I get wrong time and wrong ZONE offset information
Output of the java code
bash$ java TimeFile
Tue Dec 18 12:53:28 LKT 2007
utcTimeZone ===sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
ZONE offset ===21600000 //Should be 19800000 Since the system is in UTC+5:30
DST offset ====0
System time details
bash$ date
Tue Dec 18 12:23:42 LKT 2007
bash$ date -u
Tue Dec 18 06:53:47 GMT 2007
The java version I am using is
bash$ java -version
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)
bash$
Below I have pasted the code
public class TimeFile
public static void main(String[] args)
Calendar currentDateNTime = Calendar.getInstance();
Date date = currentDateNTime.getTime();
System.out.println(date);
int offset = currentDateNTime.get(Calendar.ZONE_OFFSET);
int dstoffset = currentDateNTime.get(Calendar.DST_OFFSET);
TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
System.out.println("utcTimeZone ===" +utcTimeZone);
System.out.println();
System.out.println("ZONE offset ==="+offset);
System.out.println("DST offset ====" + dstoffset);
}

Perhaps you should update to a newer version of Java. If you have to stick with 1.4.2, then you should at least use 1.4.2_15.
See also http://java.sun.com/javase/timezones/tzdata_versions.html on information about how to update time zone information in Java. In 2006 there was an update to the timezone info also covering Sri Lanka.
