You can use SimpleDateFormat to format date with a certain pattern with a predefined locale. For example:

Calendar cal = Calendar.getInstance(locale);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("GMT-11"));
String now = sdf.format(cal.getTime());

Try below code, may be this will help you.

DateFormat formatter= new SimpleDateFormat("MM/dd/yyyy HH:mm:ss Z");
formatter.setTimeZone(TimeZone.getTimeZone("Europe/London"));
System.out.println(formatter.format(date));

formatter.setTimeZone(TimeZone.getTimeZone("Europe/Athens"));
System.out.println(formatter.format(instance2.getTime()))
