LocalTime to UTC in JAVA

import java.text.SimpleDateFormat; 
import java.util.Date; 
import java.util.TimeZone; 
 
public class scratch { 
    public static void main (String args[]) { 
        Date now = new Date(); 
        SimpleDateFormat sdf = new SimpleDateFormat ("yyyy-MM-dd HH:mm:ss"); 
        sdf.setTimeZone (TimeZone.getTimeZone ("UTC")); 
        System.out.println ("Time in UTC is " + sdf.format (now)); 
    } 
} 

This outputs:

Time in UTC is 2011-04-11 13:40:04
