MBP M1 Time is wrong, Timezone says unknown, All timezones say the say time

I have an M1 MBP where every timezone is set to UTC time. No matter when I set to automatic time, location services are on and set it to use that time automatically. Looking through the world clock every location says it's at UTC time.

I've changed the time source, I've run the sntp command, I've deleted the plist file. This has been like this since I upgraded to Sonoma 14.4. When I change the time manually I can no longer reach internet website.

I set my current location and the timezone says unknown, so I'm assuming UTC is just the standard, no matter what I do, or how many resets, I cannot get this time to work properly.

Mac mini, macOS 13.2

You may need to reinstall macOS. This can be done without removing your personal data, though I advise you to make sure you have backed up your stuff just in case.

The process lays down a fresh copy of the macOS files, overwriting any OS files that may be damaged or corrupted.

You will find guidance for that here: How to reinstall macOS - Apple Support

one more thing to try before you re-install:

Can you connect to the Internet?

If you CAN, the INTERNAL Date&Time are likely correct, but how it is displayed TO YOU is messed up. In that case, see this article:

Change how dates, times, and more display on Mac - Apple Support

Change how dates, times, and more appear on Mac - Apple Support

The procedure is:

change the Region to a different one, NOT your own. e.g., in the UK, set to the US.

Close the window and save changes.

Change to the Region you wish to use in the long run.

Close the window and save changes.

Restart your Mac.

Test.
