My laptop (Windows 10 Education) defaults to Arizona timezone when I am at home. At work (connected to a network), it has the correct timezone and time. At home, not. All of the other computers/devices have the correct timezone.

I change to my timezone (Brisbane +10), but after a time, the timezone goes back to Arizona.

I have tried adjusting start up time to automatic in services.msc, but no luck.

Very frustrating.
Does anyone have any ideas to rectify?
