title: How to increase expiry date/time of Google Cloud Storage Objects in Django
body: <p>I have a Django REST API that uses the <code>storages.backends.gcloud.GoogleCloudStorage</code> as its <code>DEFAULT_FILE_STORAGE</code>. I noticed that media files (e.g. profile pictures of users) retrieved from any API has an <code>Expires</code> value in the URL.</p>
  <p>Here's a sample URL to a file:
  <code>https://storage.googleapis.com/&lt;BUCKET_NAME&gt;/users/a96db2f0-99a0-4691-aadb-708dc5268f77.png?Expires=1597840065&amp;GoogleAccessId=&lt;ACCESS_ID&gt;&amp;Signature=&lt;SIGNATURE&gt;</code></p>
  <p>If I convert that to an actual date, it's actually 24 hours from the time it was requested. How do I increase that to a very big time (e.g. 1 year)?</p>
