Time Zones and java.util.Date

suggest change

A java.util.Date object does not have a concept of time zone.

However, it is possible to display the date represented by the point in time described by the Date object in a different time zone using e.g. java.text.SimpleDateFormat: 

Date date = new Date();
//print default time zone
System.out.println(TimeZone.getDefault().getDisplayName());
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //note: time zone not in format!
//print date in the original time zone
System.out.println(sdf.format(date));
//current time in London
sdf.setTimeZone(TimeZone.getTimeZone("Europe/London"));
System.out.println(sdf.format(date));

Output: 

Central European Time
