This isn't so much of a tutorial, more like I made something but it requires some setup work unless I want to download a bunch of things or pay money for a subscription. Of course, I could also just give you a list of the timezones, but I'm both too lazy and too much of a tryhard for that. Enclosed, there is a python 3 file. If you don't have python 3 and don't want to get it, then you can't use it, and you can just ignore the thread, because of the above reasons. However, if you do have python, then let me tell you how to use my file. Also, I know most about macs, so this may not be helpful even if you do have python 3 and just want to use the file. You can probably just open the file and then hit f5 or fn+f5 on macs, but there is another way. If you copy the file path, which, if it is on the desktop, is on macs Users/[User]/Desktop/time.py (if you didn't rename it) terminal you can type "python3 [file path]" and hit enter. Also, if you already have python 3, chances are that you already know this. If you can actually get this to work, then I applaud both you and myself, as this is complicated. I wish I could just give the program to you and you could run it, but that's not how this works, unfortunately. Also, in case you didn't already figure it out, you need to download the file first. The first few lines of code when you open the file, probably at least one wrong thing can be seen here already, as I am not that experienced. Edit: I think I fixed the accuracy, it still isn't the most efficiently made program ever, but I tried. Also, I didn't name the timezones. Just putting that out there.
