How to update S3 bucket with expire date using AWS CLI : <p>I would like to update the S3 bucket with the new content(create a folder within a bucket). What is the <code>--expires</code> date format. I didn't find any examples using <code>AWS CLI</code> on google. Can someone please help me on this  thing?   </p>

<p>Something like this:</p>

<pre><code>aws s3 sync $backup_home s3://backup/$app-backup/$app-$DATE --expires '$DATE'
</code></pre>
