Downsides of using UTC time by setting RealTimeIsUniversal

Hi,

I have a dual-boot machine where I use both Windows 11 and Linux.

To fix a minor annoyance with the hardware RTC clock always being set to the wrong time zone whenever I switch to the other OS, I know I can make Windows use UTC time by adding the RealTimeIsUniversal entry to the registry:

reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /t REG_DWORD /d 1

What are the downsides of making this change?

Are there any known issues, other than the usual caveats about using undocumented and unsupported registry keys?
