Hello,

I use a Date field in Silverstripe and i know Silverstripe 2.4.0 use Zend_Date. But i think there is a problem with dates 1848-02-** and Zend_Date : when i display these dates, Zend_Date add +1 day each time !?

I try this code to show the problem (i think it's not a silverstripe problem) :

<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=UTF-8"/>
</head>
<body>

<?php

require_once 'Zend/Date.php';

$frDates = array(
	"31/01/1848",
	"01/02/1848",
	"02/02/1848",
	"03/02/1848",
	"01/03/1848"
);

$dates = array(
	"1848-01-31",
	"1848-02-01",
	"1848-02-02",
	"1848-02-03",
	"1848-03-01"
);

date_default_timezone_set('Europe/Paris');

print "<h1>Zend_Date (Zend Framework with Silverstripe 2.4.0)</h1>";
foreach($dates as $index => $date) {
	$oDate = new Zend_Date($date);
	$stroDate = $oDate->get('dd/MM/yyyy');
	
	$test = ($frDates[$index] !== $stroDate);
	$style = ($test ? ' style="color:red;" ' : '');
	$sign = ($test ? '!=' : '=');

	print "<div $style >" . $frDates[$index] . " $sign $stroDate</div>";
}

print "<h1>Test avec DateTime (PHP version " . phpversion() . ")</h1>";
foreach($dates as $index => $date) {
	$oDate = new DateTime($date);
	$stroDate = $oDate->format('d/m/Y');
	
	$test = ($frDates[$index] !== $stroDate);
	$style = ($test ? ' style="color:red;" ' : '');
	$sign = ($test ? '!=' : '=');
	print "<div $style >" . $frDates[$index] . " $sign $stroDate</div>";
}

?>

</body>
</html>

And the result :

Zend_Date (Zend Framework with Silverstripe 2.4.0)

31/01/1848 = 31/01/1848
*01/02/1848 != 02/02/1848
*02/02/1848 != 03/02/1848
*03/02/1848 != 04/02/1848
01/03/1848 = 01/03/1848

Test avec DateTime (PHP version 5.2.6-1+lenny8)

31/01/1848 = 31/01/1848
01/02/1848 = 01/02/1848
02/02/1848 = 02/02/1848
03/02/1848 = 03/02/1848
01/03/1848 = 01/03/1848

Snirf :'(

To resolve my problem, i've upgraded Zend to the last version (1.10.6)...

1 - I've downloaded the minimale version

2 - I've extracted the archive in a temp folder. I've got a "/tmp/ZendFramework-1.10.6-minimal" folder

3 - I've make a backup of my "sapphire/thirdparty/Zend"

mv sapphire/thirdparty/Zend sapphire/thirdparty/_Zend

4 - I've moved my last Zend version in "sapphire/thirdparty/Zend"

mv /tmp/ZendFramework-1.10.6-minimal/library/Zend sapphire/thirdparty/

It seem to work...

Do I have to modify something in Zend files so that it is compatible with Silverstripe 2.4.0/Sapphire ?

Weird - could you point us to the ticket or bugfix in Zend_framework that resolves this?
I've created a ticket for updating zend: http://open.silverstripe.org/ticket/5767
