The "time mismatch" you see is in CVS, not in Emacs. vc-cvs.el suffers from the same time mismatch because it uses the same algorithm (except it's written in elisp instead of C). I don't think vc-cvs.el should try to be more clever than CVS itself. Note that if more recent versions of w32 fixed this problem, it should be fixed for both CVS and vc-cvs.el (and pcl-cvs ;-). > Again, sorry if what I said doesn't make sense in the context of this > discussion.
