title: How do I create timestamp url or where can I find free timestamp url for MSIX app packages
body: <p>When I self sign my app packages, visual studio only allows me to create a security certificate that is valid for one year. How can I create a timestamp url or where can I find a free timestamp url to ensure the MSIX package can be installed, even after the used signing certificate has expired?

  <p>Update:</p>
  <p>I tried many urls I could find online, most of them gave me the error:</p>
  <p>SignTool Error: The specified timestamp server either could not be reached or returned an invalid response.</p>
  <p>Finally I found one (<a href="http://timestamp.comodoca.com" rel="nofollow noreferrer">http://timestamp.comodoca.com</a>) that worked from this article <a href="https://support.comodo.com/index.php?/Knowledgebase/Article/View/68/0/time-stamping-server" rel="nofollow noreferrer">https://support.comodo.com/index.php?/Knowledgebase/Article/View/68/0/time-stamping-server</a></p>
