+ <h1>How to troubleshoot time related errors on secure websites</h1>
+ <p>
+ Certificates for secure websites (the address begins with
+ <strong>https://</strong>) are valid only for a certain period of time.
+ If a website presents a certificate with validity dates that don't match
+ the date on your computer's clock, Firefox can't verify that it is
+ secure and will show you an error page.
+ </p>
+ <p>
+ Such issues can often be fixed by setting the correct date, time and
+ time zone on your computer system. If this does not solve the problem,
+ it could be caused by other issues, such as a misconfigured web server
+ or an expired certificate.
