How can i get current time of a given timezone

Question

how can i get current time of a given timezone
for example: Asia/Hong_Kong
my code is like this, but the result is not correct.
what's wrong?
import java.util.*;
public class test {
public static void main(String[] args){
          String s = "Asia/Hong_Kong";
          String tempS = "";
          TimeZone myTime = new SimpleTimeZone(s);
          //TimeZone myTime = TimeZone.getTimeZone(s);
          Calendar myCal = new GregorianCalendar(myTime);
          tempS = myCal.get(Calendar.YEAR)+"-"+
                    (myCal.get(Calendar.MONTH)+"-"+
                    myCal.get(Calendar.DATE)+" "+
                    (myCal.get(Calendar.HOUR)+":"+
                    myCal.get(Calendar.MINUTE)+":"+
                    myCal.get(Calendar.SECOND);
          System.out.println(tempS);
output is : 2001-7-15 11:16:48
but the correct time should be: 2001-8-16 7:17:48
the correct time should be 2001-8-16

Certain indexes in the Calendar API start at 0 rather then 1, so, when you get the value, you may want to increment.
I'm not sure why the time is incorrect. You may want to call getAvailableIDs() and make sure that the desired TimeZone ID is supported by your version. I doubt that Sun would have incorrect support for the time zone, but it may not be included, or perhaps it is included with a diffrent ID. You can always create your own time zone as well, by passing the String offset to getTimeZone(), the offset being how many hours beyond or before GMT. Hopefully this helps.
