I did not mean that the host time should be modified when you set the time
in the emulation. If you set the time in Hatari the host time should not be
affected.

That is a solution that also crossed my mind.

I don't intend to provide a patch, I just noticed a potential problem where
Hatari's behavior differs from real hardware and reported it. It turned out
that the software problem I stumbled upon is not caused by the date/time.
But I would not be surprised if (maybe not now but in the future) this will actually become an issue.
Best regards
