     private final static int SECOND = 1000;
     private final static int MINUTE = SECOND * 60;
     private final static int HOUR = MINUTE * 60;
     private final static int DAY = HOUR * 24;
     public static void main (String[] args)
          long time = System.currentTimeMillis();
          long days = time / DAY;
          time -= days * DAY;
          long hours = time / HOUR;
          time -= hours * HOUR;
          long minutes = time / MINUTE;
          time -= minutes * MINUTE;
          long seconds = time / SECOND;
          System.out.println (days + " days, " + hours + " hours, " + minutes + " minutes, " + seconds + " seconds");
     }Ted.
