SystemTimezoneAutomaticDetection

Unless the SystemTimezone policy turns off automatic time zone detection, then setting the policy outlines the automatic time zone detection method, which users can't change. Setting the policy to: * TimezoneAutomaticDetectionDisabled keeps automatic time zone detection off. * TimezoneAutomaticDetectionIPOnly keeps automatic time zone detection on, using the IP-only method. * TimezoneAutomaticDetectionSendWiFiAccessPoints keeps automatic time zone detection on, continually sending the list of visible Wi-Fi access-points to the Geolocation API server for finer-grained time zone detection. * TimezoneAutomaticDetectionSendAllLocationInfo keeps automatic time zone detection on, continually sending location information (such as Wi-Fi access points, reachable cell towers) to a server for the most fine-grained time zone detection. If not set, set to Let users decide, or set to None, then users control automatic time zone detection using normal controls in chrome://os-settings. Note: If you're using this policy to resolve the time zone automatically, don't forget to set GoogleLocationServicesEnabled policy to either Allow or OnlyAllowedForSystemServices.
