    Date testTime = null;
    try {
        testTime = sdf.parse(ampmtime);
        SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");
        String newFormat = formatter.format(testTime);
        return newFormat;
    }catch(Exception ex){
        ex.printStackTrace();
        return ampmtime;
    }
}
