[java] Date and time conversion to some other Timezone in java

i have written this code to convert the current system date and time to some other timezone. I am not getting any error but i am not getting my output as expected. Like if i execute my program at a particular time.. My output is ::

The current time in India is :: Fri Feb 24 16:09:23 IST 2012

The date and time in :: Central Standard Time is :: Sat Feb 25 03:39:23 IST 2012

And the actual Time according to CST time zone is ::

Friday, 24 February 4:39:16 a.m(GMT - 6:00)

So there's some time gap. and i don't know why this is happening. Any help will be appreciated.. The code is ::

package MyPackage;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;

import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;

public class Temp2 {


    public static void main(String[] args) {

        try {
            Calendar currentdate = Calendar.getInstance();
            String strdate = null;
            DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
            strdate = formatter.format(currentdate.getTime());
            TimeZone obj = TimeZone.getTimeZone("CST");

            formatter.setTimeZone(obj);
            //System.out.println(strdate);
            //System.out.println(formatter.parse(strdate));
            Date theResult = formatter.parse(strdate);

            System.out.println("The current time in India is  :: " +currentdate.getTime());

            System.out.println("The date and time in :: "+ obj.getDisplayName() + "is ::" + theResult);
        } catch (ParseException e) {
           e.printStackTrace();
        }
    }
}
