title: How to convert the date integer value of ACF plugin in WordPress?
body: <p>I am using the jQuery Date Picker of WordPress <strong>ACF Plugin</strong> to make a custom Meta Box of a custom POST. </p>
  
  <p>Now, when this Date Picker value is saved to the database table called <strong>xxx_postmeta</strong> I see that value is: </p>
  
  <p><strong>20190630</strong></p>
  
  <p><a href="https://i.stack.imgur.com/RDMlL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RDMlL.png" alt="enter image description here"></a></p>
  
  <p>So then when I get that meta value using below code: </p>
  
  <pre><code>&lt;?php echo date('F j, Y ',  get_post_meta( get_the_ID(), 'article_1_pub_date', true)) ; ?&gt;
  </code></pre>
  
  <p>then the date is showing wrong, Like this: </p>
  
  <p><strong>August 22, 1970</strong></p>
  
  <p>Is there any wrong or ACF issue?</p>
