echo new DateTime(); on wordpress causes critical error-CodePudding

If I go on my wordpress site

<?php $theCurrentDate = new DateTime(); ?>
<?php echo $theCurrentDate; ?>

It causes a critical error on my website, why?

<?php 
  try   {
     $dt = new DateTime();
     echo $dt;
  } catch (Exception $e) {
     var_dump($e->getMessage());
  }
?>

I still get critical error on site.

What is going on here? Howcome when you echo datetime() in php it breaks wordpress?

Apparently you have to specify format

<?php $theCurrentDate = new DateTime(); ?>
<?php echo $theCurrentDate->format('Y-m-d H:i:s'); ?>
