You mean the "Automatically adjust clock for daylight saving"? Wine does
not follow this silly flag and at a couple of places it depends on it. I
doubt whether it should.

This does not look correct. AFAIK RtlQueryTimeZoneInformation returns an
NT-status code, 0 is no success, otherwise it is an error code. Have a
look at GetTimeZoneInformation how to compute a TimeZoneId.
