Set time zone automatically fallback behavior when location service is disabled

Windows 11 provides a Set time zone automatically toggle in Settings > Time & language > Date & time. When enabled, the system is intended to adjust the time zone based on geographic position via the Windows Location Platform.

The feature has a permission boundary tied to location service status and network connectivity. When location data cannot be obtained, the documented behavior is to retain the last manually set zone without prompting for confirmation.

The unresolved design point is the desired behavior under location unavailability, particularly the trade-off between privacy, user control, and consistent time zone handling across consumer and enterprise-managed devices.

Should Windows 11 attempt an IP-based geolocation fallback when the location service is off or unavailable? Should the user be prompted to confirm a manual time zone change in that case? How should the user toggle interact with Group Policy overrides on managed devices?
