I tried reporting this to Apple, but they don't seem to understand it... basically trying to say I have not set it properly and it's defaulting to Cupertino - even though you can clearly see in my screenshot I attached I have it set to Chongqing China.
Also the minutes don't even match so it's impossible to just be defaulting to Cupertino time...
My guess is that Apple is still fine tuning interactive widgets. And a widget that changes constantly -as a clock must - is the height of interactivity. I’d report it and then give them time to get it right.
