Question : java get utc date/time

I need to get the UTC/GMT current date/time.  I'm using the below and it adds "-0700" at then end...is this code valid?

 private String getCurrentDate(){
        Calendar cal = new GregorianCalendar();
        cal.setTimeZone(TimeZone.getTimeZone("GMT"));
        DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
        return formatter.format(cal.getTime());
    }

result of above is 2010-05-19T16:39:15-0700
