Millis to hh:mm:ss

Question

what is the best way to display a value of milli seconds in the form hh:mm:ss
the value will only be small (a couple of minutes max);
I have tried a few different approaches, using Date and Calendar but just cant get it working. any help would be great.
cheers Paul.

Actually I think I misstated it, I believe I am 5 hours ahead of GMT and you are 1 hour behind. Can you create your own class and pass in milliseconds. For example:
import java.text.*;
import java.util.*;
public class TestTime {
   /*=**********
   * constants *
   public static long MS_SECOND = 1000L;
   public static long MS_MINUTE = 60L * MS_SECOND;
   public static long MS_HOUR = 60L * MS_MINUTE;
   public static long DAY = 24L;
   /*=**************
   * formatMilli() *
   public static String formatMilli(long value) {
      //DecimalFormat is used to display at least two digits
      DecimalFormat nf = new DecimalFormat("00");
      //calculate hours, minutes, and seconds
      long remainder = 0;
      long hours = (value / MS_HOUR) % DAY;
      remainder = value % MS_HOUR;
      long minutes = remainder / MS_MINUTE;
      remainder = remainder % MS_MINUTE;
      long seconds = remainder / MS_SECOND;
      //build "hh:mm:ss"
      StringBuffer buffer = new StringBuffer();
      buffer.append(nf.format(hours));
      buffer.append(":");
      buffer.append(nf.format(minutes));
      buffer.append(":");
      buffer.append(nf.format(seconds));
      return buffer.toString();
   }//end formatMilli
   public static void main(String args[]) {
      System.out.println(TestTime.formatMilli(5000));
      System.out.println(TestTime.formatMilli(150099999));
   }//end main
}//end TestTime classtajenkins
