Description:
------------
While trying to parse a RFC3339 datetime, PHP will generate the error "The 
timezone could not be found in the database".

It can cause problems with other systems that produce such date/time strings.

As you can see on http://3v4l.org/Bl1Kv, it affects php from version 5.2.0 to 
5.5.0.

Test script:
---------------
<?php
date_default_timezone_set('UTC');
var_dump(date_parse("2006-12-12T10:00:00.999999999-04:00"));
?>

Expected result:
----------------
array(15) {
  ["year"]=>
  int(2006)
  ["month"]=>
  int(12)
  ["day"]=>
  int(12)
  ["hour"]=>
  int(10)
  ["minute"]=>
  int(0)
  ["second"]=>
  int(0)
  ["fraction"]=>
  float(0.999999999)
  ["warning_count"]=>
  int(0)
  ["warnings"]=>
  array(0) {
  }
  ["error_count"]=>
  int(0)
  ["errors"]=>
  array(0) {
  }
  ["is_localtime"]=>
  bool(true)
  ["zone_type"]=>
  int(1)
  ["zone"]=>
  int(240)
  ["is_dst"]=>
  bool(false)
}

Actual result:
--------------
array(13) {
  ["year"]=>
  int(2006)
  ["month"]=>
  int(12)
  ["day"]=>
  int(12)
  ["hour"]=>
  int(10)
  ["minute"]=>
  int(0)
  ["second"]=>
  int(0)
  ["fraction"]=>
  float(0.99999999)
  ["warning_count"]=>
  int(0)
  ["warnings"]=>
  array(0) {
  }
  ["error_count"]=>
  int(1)
  ["errors"]=>
  array(1) {
    [0]=>
    string(47) "The timezone could not be found in the database"
  }
  ["is_localtime"]=>
  bool(true)
  ["zone_type"]=>
  int(0)
}
