Bug #73426 createFromFormat with 'z' format char results in incorrect time
Submitted: 2016-10-31 07:54 UTC Modified: 2016-10-31 10:31 UTC
From: vaclav dot sir at gmail dot com Assigned: derick
Status: Closed Package: Date/time related
PHP Version: 7.1.0RC5 OS:
Private report: No CVE-ID:
 [2016-10-31 07:54 UTC] vaclav dot sir at gmail dot com
Description:
------------
When you use the 'z' format character after the time ('H:i:s z'), the time information gets parsed incorrectly. If you use the 'z' char in front of the time ('z H:i:s'), it parses fine.

Affected versions are 7.1.0RC4 and 7.1.0RC5: https://3v4l.org/QOS7s

Test script:
---------------
<?php

$date = '12:00:00 15';
$format = 'H:i:s z';

var_dump(DateTime::createFromFormat($format, $date));

Expected result:
----------------
object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2016-01-16 12:00:00.000000"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(16) "Europe/Amsterdam"
}

Actual result:
--------------
object(DateTime)#1 (3) {
  ["date"]=>
  string(31) "2016-01-16 11:59:55.-2147483648"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(16) "Europe/Amsterdam"
}
