Set timezone based on current location not working in Mac OS Catalina after windows10 installation with bootcamp, why?

Hello, this is Stephen. I have a question, I installed windows10 with bootcamp assistant, and after setting up windows, I booted back into mac oS and noticed that the clock was off by an hour. I went into date and time in system preferences and clicked on timezone, and I noticed that the timezone was set on Pacific standard time, I'm in mountain time. I also noticed that the, set timezone based on current location feature wasn't setting the timezone back to Mountain time, this problem started when I installed windows10, something must have went wrong during the installation and setup. I have tried everything from resetting the PRAM and SMC to reformatting and reinstalling the operating system, and it still doesn't work. Anyone know how to fix this problem? I called Apple support and they weren't able to figure it out and have escalated my case to the engineers, I have also noticed that internet recovery won't load either, I had to reinstall mac oS with a bootible installer usb drive because internet recovery wasn't working. I checked that my internet connection was working, nothing wrong their. Any help would be greatly appreciated, thanks in advance. Macbook air, 2017, Mac oS Catalina, 10.15.2
