I followed a video's tutorial on something and it told me to change my date and time, so I did. After switching back to the current date, none of my browsers are loading webpages correctly, all of them saying that my clock is incorrect, even though it isn't. There are very few exceptions to this, like YouTube and Google. Even applications like Steam aren't working properly and trying to synchronize with any internet time server that Windows shows by default isn't working. It only brings up an error. I feel like I messed something up royally by changing the clock to that time. Could someone please help?
