Unix time is the number of seconds since 1 January 1970, so this should work

Date date = new Date(unixTime * 1000);
String str = new SimpleDateFormat("dd/MM/yyyy").format(date);

BTW SimpleDateFormat accepts millis as argument too, so it is possible to get the same result as

String str = new SimpleDateFormat("dd/MM/yyyy").format(unixTime * 1000);

Do `unixTime * 1000L` to make sure to not lose data in the multiplication. – Erik Ekman Jul 18 '13 at 11:43
Theoretically yes, but only if OS supports leap seconds – Evgeniy Dorofeev Jul 18 '13 at 11:44

If the `unixTime` is `int`, it will overflow if multiplied by the int 1000. If the constant 1000 is `long` it will not matter. – Erik Ekman Jul 18 '13 at 11:47

    Date date = new Date(time);
    DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
    format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
    String formatted = format.format(date);
    System.out.println(formatted);
