Then it's a known problem that's pretty hard to fix:

w32 handles DST by changing the definition of "time 0", so during the
DST-change things behave as if all the files's timestamps had been changed
by 1 hour.

So there really is a 1-hour difference between what the CVS/Entries file
says and what the file's time stamp says.  We could try to be more clever
with such situations, but since it's basically a case of braindamage in the
w32 "spec" I'd rather not bother.
IIRC "cvs update" will fix things for you.

PS: Note that last I heard `cvs status' has to send the file over to the
    server in order to figure out that it's up-to-date, because it uses the
    exact same algorithm as vc-cvs.el to decide whether a file was touched
    or not.  You can figure that out with "cvs -t status":

% cvs -t status INSTALL.CVS 
  -> main: Session ID is Mg0eb0F9FW12DMKr
  -> main loop with CVSROOT=/sources/emacs
  -> open_connection_to_server (cvs.sv.gnu.org:/sources/emacs)
 -> Starting server: ssh-cvs cvs.sv.gnu.org cvs server 
  -> rename(CVS/Entries.Backup,CVS/Entries)
  -> unlink_file(CVS/Entries.Log)
S -> serve_directory (.)
S -> dirswitch (., /sources/emacs/emacs)
