Your phone will be correct, but your PC may not be. Go into the Date&Time control panel and make sure Set Time Automatically is ON. Then hit the Sync Now button.

My Casio wristwatch does that. It’s also also solar-powered so it never need batteries. I use it for clocks that need to be set manually.

(I also still have a Sony ICF-2010 shortwave radio. I used to listen programs on the BBC World Service.)
