Probably, but even Windows would break in this scenario. It interprets the hardware clock as being in local time and derives UTC from that (you can change that with a registry change, but it isn't very reliable in my experience)

Keeping the clock in UTC is reliable on Windows 10/11. Windows will happily read and write to the clock in UTC, and things like NTP sync just work.
