PHP Bug Type: Date/time related
Bug description: DateTimeZone::getTransitions output different on 64 bit
Description:
------------
First entry in array returned by DateTimeZone method getTransitions (and
function timezone_transitions_get()looks bogus on 64 bit systems. I
expected same result when running this command on 32 and 64 bit systems.
Problem affects current levels of PHP 5.3 and 6.0 (snapshot timestamp ==
Wed 22-04-2009 6:30:00 ) only.
Looks like problem caused by use of constant LONG_MIN at around line 3218
in current src of ext/dates/date.c introduced by the following change:

- MFH: Fix the DateTimeZone::getTransitions() algorithm.
======================================================================
Reproduce code:
---------------
<?php
date_default_timezone_set("Europe/London");
$tz = new DateTimeZone("Europe/London");
$tran = $tz->getTransitions();
var_dump( $tran );
?>
Expected result:
----------------
(as produced by same code running on Linux 32 bits system)
array(243) {
[0]=>
array(5) {
["ts"]=>
int(-2147483648)
["time"]=>
string(24) "1901-12-13T20:45:52+0000"
["offset"]=>
int(3600)
["isdst"]=>
bool(true)
["abbr"]=>
string(3) "BST"
}
Actual result:
--------------
array(243) {
[0]=>
array(5) {
["ts"]=>
int(-9223372036854775808) <- == LONG_MIN
["time"]=>
string(30) "-219246529-01-27T08:29:52+0000" <- Bogus looking entry
["offset"]=>
int(3600)
["isdst"]=>
bool(true)
["abbr"]=>
string(3) "BST"
}
