If you specifically need to know when Next.js last built a static page, you could store the build timestamp in an environment variable at build time and access it in your page. Would be better in this case..

Additionaly you can use the built-in generateMetadata like this example:

  // get current server timestamp
  function getTimestamp() {
  return new Date().toLocaleString();
   }

  export default function Page() {
  // frozen at time your app build for static pages
 // or evaluated at request time for dynamic pages *see the end lines*
 const timestamp = getTimestamp();
  
 return (
 <div>
  <h1>Your next Page</h1>
   <p>Page was generated on: {timestamp}</p>
  
     {/* Rest of your page content */}
                                </div>
        );
       }

      //  To ensure the page is dynamic and shows the actual render time
          export const dynamic = 'force-dynamic';

       // To revalidate at in intervals
         export const revalidate = 60; // revalidate every x seconds

And for a more advance feature you can add in as a Server Component context.
