I can't reproduce this issue.  I have files created during summer time
as well, on my Linux machine and my Cygwin box.  The output of ls -l
in Linux and Cygwin is identical for the files on the Samba share,
and the timestamps of Windows and Cygwin are identical as well.

Are the timezone settings on the remote machine and the local machine
identical?
