Problem with SimpleDateFormat

Question

Hi all,
I would like to parse a time (00:00:00) in String format into a Date obj. I am using the following code to achieve it. however, the result come out is not what i expect.
   String fromTimeStr = "00:00:00";
   TimeZone sg = TimeZone.getTimeZone("Asia/Singapore");
   System.out.println("Timezone "+sg);
   SimpleDateFormat DF = new SimpleDateFormat("HH:mm:ss");
   DF.setTimeZone(sg);
   Date time = DF.parse(fromTimeStr);
   System.out.println("DAte time"+ time);the output is as followed:
Timezone sun.util.calendar.ZoneInfo[id="Asia/Singapore",offset=28800000,dstSavings=0,useDaylight=false,transitions=8,lastRule=null]
DAte timeThu Jan 01 00:30:00 GMT+08:00 1970
From what i know, the timezone of Singapore is fallen within the GMT+8 zone; thus the result should be Jan 01 00:00:00 GMT+08:00 1970
My system timezone is "Kuala Lumpur\Singapore GMT+8".
Could someone enlighten me what there is 30 minutes extra from the output.
Thanks

This is basically what I'm doing:
package test;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateFormatError
     private SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
     private Date dateOfBirth;
     public static void main(String[] args)
          DateFormatError x = new DateFormatError();
          x.run();
     public void run()
          String dob = "10/06/1989";
          try
               dateOfBirth = sdf.parse(dob);
          catch (Exception e)
          sdf.format(dateOfBirth);
          System.out.println(dateOfBirth.toString());

try {
  // something that may throw an exception
} catch(AnException e) {
  // do nothing with it: ie, swallow it
}because whenever something goes wrong, you will not notice it since nothing is even printed to the screen: this makes debugging your code very hard! Always at least print the stack trace:
try {
  // something that may throw an exception
} catch(AnException e) {
  e.printStackTrace();
}so you will see some helpful message on your screen when something goes wrong.
Good luck!
