SimpleDateFormat ignores “XXX” if timezone is set to “UTC”
I am trying to output the current datetime as UTC in the following format: 2016-01-11T14:08:42+00:00 final SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX"); formatter.setTimeZone(TimeZone.getTimeZone("UTC")); final String dateString = formatter.format(new Date()); "dateString" should now contain "2016-01-11T14:08:42+00:00" but it contains "2016-01-11T14:08:42Z". Without the "UTC" timezone setting I get the right format but - of course - in my specific timezone... Any ideas? See the documentation for SimpleDateFormat : For formatting [using an ISO 8601 Time zone],
