Whether you are gathering information on the internet, or just passing time by watching some entertaining content on various Websites and Platforms, errors can find their way into whatever you may be working with. Some of these errors are easy to deal with, while others tend to be more pesky and annoying as they require extreme and comprehensive methods to be removed.

NET::ERR_CERT_DATE_INVALID is an error that appears when you open Google Chrome. This error doesn’t allow any browsing to take place, hence your work is severely hindered and interrupted, this also means you cannot bypass it without fixing or ignoring it. This error is more commonly known as the ‘Your clock is ahead/behind error’ and it indicates that your computer system has an invalid date or time. This prevents you from accessing the internet because it is an SSL error.

SSL stands for Security Sockets Layer and its main purpose is to establish a secure relationship between the server and the client. The SSL error occurs when a browser can not verify the SSL Certificate, this means that a secure connection can not be established. A device’s outdated date or time, or even if its date or time is ahead of the actual time, can very well cause an SSL error, this means a secure connection cannot be made and you cannot access the internet using Google Chrome. Chrome is all about maintaining a person’s security and giving them privacy, while also allowing them freedom over site settings etc. So in order to ensure that any exchange of information over the internet is safe, the developers have placed protocols and measures, which can be violated when your system date and time are not valid.

There are reasons why your date and time are invalid and they are specified below:

  • Using a device that hasn’t been turned on in a while: It could be that the device you are using hasn’t been turned on in ages and due to the lack of internet connection, it wasn’t able to keep up with the actual date and time.
  • Malware affecting your date and time: There is a possibility that malware might be maliciously changing your date and time or even the time zones.
  • Wrong Timezone: You might be in a different timezone and the timezone on your computer may be a different one.
  • The browser cache might be too large: Cache and cookies are there to make our experience faster. However, if their memory exceeds a certain limit they tend to cause many problems on a Web Browser.
  • Faulty CMOS battery:  CMOS stands for ‘Complementary Metal Oxide Semiconductor’ and the purpose of the CMOS battery is to keep the BIOS running even when the computer is unplugged.
  • SSL certificate is outdated: It is a digital certificate that allows us to have a secure connection by authenticating a website’s identification.

Change the CMOS Battery

The BIOS needs to stay functional even when the device is turned off. In order to keep the BIOS running the complementary metal-oxide-semiconductor or the CMOS battery tends to power the BIOS. This allows the BIOS to retain its contents and keeps the system up to date even when the computer is not working. CMOS battery also helps maintain the actual date and time of a system, if no other solution works then most probably your CMOS battery is busted and is in need of repair or replacement. Replacing or repairing any part of any machine is a difficult job, and requires some skill and experience. If you don’t know what you are doing, we do not recommend performing surgery on your device, instead, it is easier and less stressful to allow someone who knows the intricacies of the inner workings of a computer to deal with this.

Reinstalling the SSL certificate

As we discussed earlier, the Secure Socket Layer or the SSL is a protocol, which ensures that the internet connection is secure and safe from all sorts of vulnerabilities. The SSL certificate is a form of authentication of an identity of a website and it also enables a secure connection between the user and that website. An SSL error occurs when the secure connection isn’t established, as the verification of these certificates cannot be done. The ’Clock is behind/ahead’ or the NET::ERR_CERT_DATE_INVALID  is also an SSL error, hence it is possible that your SSL certificate may very well be expired. Simply reinstalling the certificate will do the trick and get rid of this error.

By using most of these fixes, you will be able to get rid of the NET::ERR_CERT_DATE_INVALID  error on Google Chrome and you can get back to using your favorite browser, to surf across the internet for whatever reason you may be accessing it.
