ZF-5753: Zend_Date returns Week number with 2 digits


With SVN14051:

require_once 'Zend/Date.php';
$date = new Zend_Date(1234567890); // => 2009-02-14
echo $date->toString('w');

This echoes '07' instead of '7' (based on…).

In Zend_Date, line 843:

// week formats
case self::WEEK :
    return $this->date('W', $this->getUnixTimestamp(), false);

With newer PHP versions, 'W' is always return with 2 digits (see resolved in PHP 5.1.0).

Based on ISO8601, we must have 2 digits, so I think we should remove the possibility of only one digit since it does not function.


Wrong behaviour of PHP fixed with r14060
