Why does being able to load websites / browse internet depend on my computer’s clock being right?

451 viewsOtherTechnology

I notice that if I’ve traveled and my computer’s system clock is wrong by time zone, or I have not started up a computer in a long time (battery went dead) and its clock is wrong, that computer will not even be able to visit regular old websites on the internet (to look up information, what time it is, etc).

But if I reset the clock to approximately the correct time, things are back to normal. Why does it depend on this?

SSL certificates are valid for a year. If you’re running your pc with a date outside that range it will consider the key to not be valid and block you from continuing.
