Hi Kellby,
Like you my time and date were correct but after trying everything else I had to give it a go and low and behold, it's done the trick. I simply went into my date settings and re-selected the same date and somehow this has solved the problem and all my apps are opening so even if your date and time settings are correct it still may be worth a try as it worked for me!
