I live in Arizona. We only do MST here. Despite this, during the recent daylight savings time switchover this weekend, my phone decided to update itself to MDT. This was not fixed until I went off airplane mode. This caused me to end up waking up an hour earlier than when my alarm was supposed to be set.

The automatic timezone should be switched over to be GPS based, instead of being entirely reliant on the cell network (and having the ability to reach it).

    benjistokman enabling network location might fix that as it may only use that instead of GPS to save power and work indoors. You can enable it from Settings > Location > Location services > Network location.

      I had my timezones change unintentionally when I was connected to another country's VPN server which I think what caused it

      benjistokman Oh no I mean the system may only use the network location provider for that feature, apparently that was the case with the automatic Wi-Fi on feature at least.
