Fedora hardware real-time clock setting for dual-boot with Windows

The goal is to maintain consistent wall‑clock times when Fedora and Windows share the same machine.

Fedora’s default configuration keeps the hardware real‑time clock (RTC) in UTC, while Windows expects the RTC to store local time. This mismatch leads to incorrect time display after booting the other OS, and the decision of which RTC mode to adopt remains unresolved for dual‑boot scenarios. The interaction with NTP synchronization, daylight‑saving transitions, and containerized workloads adds further uncertainty about the appropriate policy.

What are the implications of changing the RTC mode with timedatectl set-local-rtc 1 on NTP‑driven clock stability?
How should administrators verify that both operating systems show the same time after each boot without manual correction?
Is there a recommended fallback strategy for systems that occasionally boot Windows only?
