title: Strapi - get last content changed date
body: <p>I'm building a website and would like to use strapi CMS as the backend. Since my website will be built with Gatsby, I planned of using a cron task on the server to build the website every day, if the content has changed.</p>
  <p>Is there a functionality in Strapi that let me retrieve the last content changed date? Or should I create it myself (if it's possible)?</p>
  <p>EDIT:</p>
  <p>Sadly, I can't use webhooks because I'm forced into a PLESK control panel.</p>
