... with Windows DST bug IMO the most annoying:

(C:NTFS, F:FAT)

$ cd /cygdrive/c

$ ls -l --full-time test-* | cut -c 28-
2007-01-01 12:00:00.000000000 +0100 test-jan
2007-06-01 12:00:00.000000000 +0200 test-jun

$ cmd /c dir test-* | grep test-
01.01.2007  13:00                 0 test-jan
01.06.2007  12:00                 0 test-jun


$ cd /cygdrive/f

$ ls -l --full-time test-* | cut -c 28-
2007-01-01 11:00:00.000000000 +0100 test-jan
2007-06-01 12:00:00.000000000 +0200 test-jun

$ cmd /c dir test-* | grep test-
01.01.2007  12:00                 0 test-jan
01.06.2007  12:00                 0 test-jun


Wait until next DST change and enjoy 1 hour time shifts in the opposite 
direction.

Cygwin's time stamps are OK on NTFS,
Windows' (cmd, explorer, msvcrt's stat()) on FAT.

Is this fixed on Vista? Bug was still present on Vista RC1.
