Zend Date Weirdness - Missing Configuration?

Question

I'm getting odd output from the getDate() function. It's supposed to return a date without the time parts, but I am getting time parts. Am I missing some configuration option that would correct this?

Sample Code:

date_default_timezone_set('America/New_York');
$date = new Zend_Date(array(
    'year' => 2010,
    'month' => 3,
    'day' => 29,
));
echo $date->getIso() . PHP_EOL;
echo $date->getDate()->getIso() . PHP_EOL;

Output:

2010-03-29T00:00:00-04:00
2010-03-29T23:00:00-04:00

Answer 1

This isn't really an answer to my question, but this is my workaround. I have extended the Zend_Date class as follows:

class My_Date extends Zend_Date
{
    public static function now($locale = null)
    {
        return new My_Date(time(), self::TIMESTAMP, $locale);
    }

    /**
     * set to the first second of current day
     */
    public function setDayStart()
    {
        return $this->setHour(0)->setMinute(0)->setSecond(0);
    }

    /**
     * get the first second of current day
     */
    public function getDayStart()
    {
        $clone = clone $this;
        return $clone->setDayStart();
    }
}
