许多网站使用证书既是安全的又表明它们是安全的。它们的URL以HTTPS开头。现在，该安全证书由发行机构在一定期限内发行。现在，如果您在Firefox 浏览器^{(Firefox browser)}中看到此类错误，那么您肯定会对这篇文章感兴趣。

排查^{(Troubleshoot)}Firefox安全网站上与时间相关的错误

要确认Firefox中的问题是否是由于与时间相关的错误，请单击高级^(Advanced)并检查错误代码。如果发生与时间相关的错误，错误代码将是以下代码之一：

• SEC_ERROR_EXPIRED_CERTIFICATE

• SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE

• SEC_ERROR_OCSP_FUTURE_RESPONSE

• SEC_ERROR_OCSP_OLD_RESPONSE

• MOZILLA_PKIX_ERROR_NOT_YET_VALID_CERTIFICATE

• MOZILLA_PKIX_ERROR_NOT_YET_VALID_ISSUER_CERTIFICATE

查看系统时间^{(Check the time on system)}

现在由于错误与时间有关，我们的第一种方法应该是检查时间。如果不正确，请使用以下步骤进行更正：

1. 单击^(Click)“开始^(Start)”按钮，然后单击像符号一样的齿轮以打开“设置”^(Settings)页面。
2. 在列表中，请从可用选项中选择时间和语言。^{( Time and Language)}
3. 将自动设置时间^{(Set time automatically)}选项设置为开。
4. 重新启动系统。

如果这不会更改时间和日期，请在同一设置页面上手动执行相同操作。您也可以考虑验证时区和位置。

1. 为此，请单击日期和时间^{(Date & time)}设置页面上的其他日期、时间和区域设置。^{(Additional date, time, and regional settings)}
2. 选择选项选择时间和日期^{(Select the time and date)}或更改时区^{(Change the time zone)}以手动修改设置。

联系网站所有者^{(Contact the website owner)}

如果更改日期和时间没有帮助，则可以提醒网站所有者检查其证书是否已过期。

绕过警告^{(Bypass the warning)}

出于安全原因，不建议这样做 - 但如果您愿意，如果您信任该网站，有一种方法可以做到。

1. 单击警告页面上的Advanced，然后单击Add Exception。
2. 单击查看^(View)，然后单击确认安全异常^{(Confirm security exception)}。
