I am a bit confused. I assume that this worked correctly in previous
years when the time shifted. So I assume this is a problem where Linux
has been updated so that it knows the new time change dates, but Wine is
still using the old ones. Does that sound right?
I don't think anyone here is going to be able to help with Wine from
2004, so I think you are going to need to find out where Wine from that
vintage keeps the timezone info, and modify it. I know that MS provides
the utility tzedit.exe for changing the timezone info in Windows2k.
Maybe it will work on Wine?
