New Comment:
It looks bogus, but it is (sortof) correct. If you go
-9223372036854775808 seconds back from 1970-01-01 you end up at a date
219 billion years in the past. Not sure why it formats wrong though.

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:

Revision 1.43.2.45.2.51.2.28 - (view) (download) (as text) (annotate) -
[select for diffs]
Thu Mar 20 19:43:36 2008 UTC (13 months ago) by derick
Branch: PHP_5_3
Changes since 1.43.2.45.2.51.2.27: +57 -24 lines
Diff to previous 1.43.2.45.2.51.2.27 , to branch point 1.43.2.45.2.51
- 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"
}
