Convert date to different timezone [duplicate]

Answer 1

When you print the date using System.out.println(date); or System.out.println(instance2.getTime());, the Date returned by instance2.getTime() is TimeZone independent and always prints the date in local timezone.

Instead you may want to use DateFormat/SimpleDateFormat:

  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()))
