Understood and agreed.  However, this confusion started when you
claimed that FindFirstFile did not return UTC times, but local times.
I hope now we agree that it does return UTC times, except that those
times are sometimes off by one hour due to the incorrect DST
correction.

I meant the _function_ `stat' as implemented in Emacs's w32.c.  I did
not mean the _program_ `stat' that is part of Coreutils.

If you can step with a debugger through the function `stat' in w32.c
and see what times it returns for your files, it'd be great.

Not really.  It's quite obvious that `stat' the program converts the
times to local time for display (witness the +0200 etc. time-zone
offsets it shows).  I need to see the raw times returned by the
FindFirstFile API.

Anyway, I'm not sure anymore whether we should pursue this issue any
further, especially since Stefan thinks we shouldn't try fixing this.
