    You can use java.util.Calendar for this. It offers a setTimeZone() method (which is by the way superfluous since it by default already picks the system default timezone).

    long timestamp = 1245613885;
Calendar calendar = Calendar.getInstance();
calendar.setTimeZone(TimeZone.getDefault());
calendar.setTimeInMillis(timestamp * 1000);

int year = calendar.get(Calendar.YEAR);
int day = calendar.get(Calendar.DATE);
int hour = calendar.get(Calendar.HOUR_OF_DAY);
int minute = calendar.get(Calendar.MINUTE);

    If you’d like to present it in a human readable date string, then I’d suggest SimpleDateFormat for this.

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String dateString = sdf.format(calendar.getTime());
System.out.println(dateString); // 2009-06-21 15:51:25

    (the output is correct as per my timezone GMT-4)
