Bug description: Australia/Victoria timezone is wrong this week
Description:
------------
On PHP 5.1.6 and 5.2.4, strftime is returning the wrong information on my
Linux systems in the Australia/Melbourne timezone.
We recently had a change to the rules for daylight savings which extended
daylight savings by one week from Sunday 30 March to Sunday 6 April.
The operating system has handled this change fine (using tzdata 2007k),
but PHP is wrongly reporting the timezone as UTC+10 instead of UTC+11.
I have seen PHP default to Australia/Melbourne and Australia/ACT on
various systems, but all of those will be at UTC+11 until this weekend.
The only timezone that is correctly UTC+10 is Australia/Brisbane.
Calling date_default_timezone_set('Australia/Melbourne') does not solve
the problem.
The attached code produces the following output:
PHP time: 3 Apr 2008 9:48
shell time: 3 Apr 2008 10:48
It shows that the system's time and timezone is correct, but PHP is doing
something whacky. Does it have its own tzdata? (And if so why?)
Reproduce code:
---------------
<?php
date_default_timezone_set('Australia/Melbourne');
$user_datetime_format = "%e %b %Y %k:%M";
$now = time();
$current_time = strftime($user_datetime_format, $now);
$offset = strftime("%z", $now);
print("PHP time: $current_time\n<br>");
print("shell time: ");
system("date \"+$user_datetime_format\"");
?>
Expected result:
----------------
PHP time: 3 Apr 2008 10:48
shell time: 3 Apr 2008 10:48
Actual result:
--------------
PHP time: 3 Apr 2008 9:48
shell time: 3 Apr 2008 10:48
