Alternatively, you can create a bootable DOS USB drive for BIOS update.
Now, restart your PC and the you should not see the error again.
Alternatively, you can temporarily change the time zone through the Settings app and check if it resolves the internet time sync issue. If that doesn’t work, you can check if there any pending Windows update to be downloaded and installed. If there is, download and install the update, and then restart your PC to check if it corrects the time issue on your Windows 10 PC. Sometimes, the issue can arise due to your computer battery. If the BIOS is corrupted, it can create the time and date settings issue. To check if you battery is an issue, enter BIOS (refer to this article on how to enter BIOS). If there’s an issue with the battery, you would need to replace it. However, if this method also fails, check if the CMOS battery needs to be replaced. Make sure you seek help from a technician for the CMOS battery replacement.
