When I googled earlier, all answers pointed towards the phone receiving cellular signals or depending on its internal digital clock but I’m asking this question because when we crossed my country’s border and briefly entered our neighbor’s territory, my phone’s time automatically changed to the neighboring country’s timezone even though there was absolutely zero cellular service and I didn’t have mobile data or location turned on (not that mobile data would have worked without cell service)
So, how did my phone know the other country’s time? I don’t really understand how the internal clock works either, but this is even more of a mystery to me. Would love to know how this really works!

Your phone almost certainly has a built in GPS. Depending on the device, switching off “location services” may shut off access to software, but it is unlikely that the GPS itself is shut off.
So, since the clock is almost certainly part of the OS, it can be given access to all sorts of information that is not being shared with third party apps. Information like the GPS data that’s otherwise being withheld.
