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!

I don’t know what setting exactly you mean by “location”, but it’s likely you only turned off the use of local cellular/wifi signals, not GPS itself. So it probably used its internal clock to keep time and the GPS position to set the time zone.
