While in ArtEx, we dive a bit deeper, and we look for the timezone change from logd.0.log. When iOS devices are first booted, or booted after a wipe, the timezone is automatically Pacific time. Why? Because that is where Apple is. When the user opts to set the timezone, this file is updated. Hence, it’s a fantastic file to see when the device was first booted. If the user lives in Pacific time, rely on the other artifacts mentioned.
