Get Publish Date Not Modified Date

How do I get the date the post was published? All the WordPress functions seem to only pull the post_modified date.

This is what I am doing:

$myposts = get_posts([
  'post_type' => 'fiveminutespodcast',
  'post_status' => 'publish', 
  'numberposts' => -1,
  'orderby' => 'title',
  'order'    => 'ASC'
]);
foreach ( $myposts as $post ) :
		$mytitle = get_the_title($post);
		$url = get_permalink($post);
		$date_time = get_the_date('M j, Y');
		echo "<a href='$url'>$mytitle</a> ($date_time)<br>";
endforeach; 

But this keeps pulling up the post_modified date – or so it seems.
