That's interesting, Zend_Date#isLater() is supposed to return a boolean. I
just confirmed this with a quick unit test:
public function testZendDateIsLaterReturnsBoolean()
{
$date1 = new Zend_Date();
$date2 = new Zend_Date();
$result = $date1->isLater($date2);
$this->assertTrue(is_bool($result));
}
Is that maybe a var_dump of something else? Looks like a dump of $context.
