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

504 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?

One thing that no one else seemed to mention is that there was a recent push by web browsers to prefer secure connections and use HTTPS to try to better protect people’s information online.

So maybe ten years ago, secure connections for “normal” pages weren’t that common, but they were for ones where you entered credit card info or other important information. Nowadays, most connections use secure connections.
