AFAIK, the internal time is in GMT (UTC?) for all users in all time zones.
The time you see is adjusted to reflect your own *current* time zone when
it is displayed, but the stored time is unchanged. There might be a
configuration item (but I doubt it) to leave the display time unchanged
when the file creation time/date was outside of DST.
If I'm correct, the only files affected will be those mode when DST was not
in effect, and the comparisons will work correctly anyway.
If the above is true, then touch.exe might create chaos if used.
In my view, this is a bug, of course.
BTW, I can't verify what happens on my computer, because I don't know the
correct times of any of my files to check them out: there's nothing
critical involved here and I haven't had to keep track.
