Java - How to set timezone of a java.util.Date

Use DateFormat. For example,

    SimpleDateFormat isoFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
    isoFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
    Date date = isoFormat.parse("2010-05-23T09:01:02");

Be aware that java.util.Date objects do not contain any timezone information by themselves - you cannot set the timezone on a Date object. The only thing that a Date object contains is a number of milliseconds since the "epoch" - 1 January 1970, 00:00:00 UTC.
As ZZ Coder shows, you set the timezone on the DateFormat object, to tell it in which timezone you want to display the date and time.
