body: <p>How to extend the duration of the token ? I have function with expired time but not work correctly. </p>
  
  <pre><code>    protected function respondWithToken($token)
      {
          return response()-&gt;json([
              'token' =&gt; $token,
              'token_type' =&gt; 'bearer',
              'expires_in' =&gt; auth()-&gt;factory()-&gt;getTTL() * 464465353454316000,
              'user' =&gt; auth()-&gt;user()
          ]);
      }
  }
  </code></pre>
  
  <p>The token expires very quickly.</p>
  
  <pre><code>'expires_in' =&gt; auth()-&gt;factory()-&gt;getTTL() * 464465353454316000 //this line not work property. Token expired early
  </code></pre>
