Documentation says "timezone: Time zone ID, default is system default."

The "system default" really means only the "TZ" environment variable on Unix/Linux systems. It does not mean PHP ini setting or value set via date_default_timezone_set() or the OS default time zone in file "/etc/timezone".

It should be noted that the locale string passed into IntlDateFormatter's constructor supports UCA keywords. So you can, for example, do things like this to output the year as a Japanese era year:

<?php
$now = new DateTime();    //DateTime is a core PHP class as of version 5.2.0

$formatter = new IntlDateFormatter('ja_JP', IntlDateFormatter::FULL,
        IntlDateFormatter::FULL, 'Asia/Tokyo', IntlDateFormatter::GREGORIAN);

echo 'It is now: "' . $formatter->format($now) . '" in Tokyo' . "\n";
//above gives [It is now: "2011年8月19日金曜日 23时32分27秒JST" in Tokyo]

$formatter = new IntlDateFormatter('ja_JP@calendar=japanese', IntlDateFormatter::FULL,
        IntlDateFormatter::FULL, 'Asia/Tokyo', IntlDateFormatter::TRADITIONAL);

echo 'It is now: "' . $formatter->format($now) . '" in Tokyo' . "\n";
//above gives [It is now: "平成23年8月19日金曜日 23时32分27秒JST" in Tokyo]
?>
