Your computer is using the computers time for a lot of internal operations. For a typical user the time is usually not that important and may not be more than a simple watch but for your computer it is necessary to know what time it actually is right now. Normally you do not need to put hands on it but if the time stops working or is out of sync, you will run into tons of issues. For example: when you visit a secure site that has the https:// in it, it will sync time to validate the security certificate. https:// links use, certificates to encrypt data sent to and from your computer.
If for any reason your browser “Google Chrome“, cannot sync or verify the time you will run into this error -> ERR_CERT_DATE_INVALID. In this guide, we will list the steps to address this issue. The methods listed in this guide are applicable to all versions of Windows.
Phase 1: Synchronize the Time
Click the Start button and type cmd. Right Click cmd and choose run as administrator. If you are running Windows 8 or 10, Hold the Windows Key and Press X. Choose Command Prompt (Administrator)
In the black command prompt window which opens up, type the following commands.
sc config w32time start=demand
net start w32time
You can also manually adjust the time if you want, by clicking the clock-icon.
Phase 2: Disable avast! HTTPS-Scanning (If you are running avast!)
avast! is tight with security, with tons of rules. Personally, in my opinion the features they have built into avast! results in issues rather then solutions and they should not be used for a home-user. Since many users have reported the issue originating from the HTTPS scanning feature in avast! and disabling it has resolved it for them, this is what we’re going to do in Phase 2.
Click Start, type avast and choose avast from the results displayed. Once the avast window opens up, Go to settings (upper right, wheel-icon) and choose Active Protection then choose Web Shield (Customize) and from here Disable HTTPS scanning. If you are running a different antivirus, try looking for web or http or browser scan feature within settings, and disable it.
Phase 3: Restart your computer
To make sure all the changes you made are actually working, restart your computer. After the computer has rebooted, test and see if the issue is now resolved.
