I got this to work. Let me know if it works for you. Seems like a lot of lines to do something seemingly simple..

    int millis = 5000;
    TimeZone tz = TimeZone.getTimeZone("UTC");
    SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss");
    df.setTimeZone(tz);
    String time = df.format(new Date(millis));
    System.out.println(time);
