title: AWS Route53: Get DNS record set creation time
body: <p>I use Python SDK to delete DNS record sets in <code>Route53</code>. Due to <code>Route53</code> API throttling, the deletion fails sometimes and the stale DNS record set is building up.</p>
  
  <p>As the DNS record set approaches the 10,000 limit, I want to delete the record sets that were created last year because they are not needed any longer. But I am unable to find the record creation time either using <code>AWS CLI</code> or using Python SDK (<code>Boto3</code>). Is there a way to get the DNS record creation time in <code>Route53</code> using <code>CLI</code> or <code>SDK</code>?</p>
