Full_Name: Neil L. Roeth OS: Solaris/SunOS 5.5 Version: 20.4 severity: Serious Submission from: (NULL) (205.228.12.71) Y2K problem in vc-hooks.el I use Tools/Compare/File With Revision... with my currently checked out revision in the current buffer. I choose the defaults, use latest revision and current buffer, and the revision that get checked out is not the latest, it is the last revision in 1999. I isolated the problem to vc-fetch-properties, when it calls vc-parse-buffer. It does not parse the RCS dates correctly; the dates for 1999 have a two digit year (99) and the dates for 2000 have the full four digits. A local elisp expert said the vc code is taking the two date/time strings and doing a lexical compare on them. This bug makes comparing files very confusing, when you think you've changed a few lines, but many show up in the ediff. I have not checked, but I would guess there are other effects, since vc-hooks.el provides general vc functionality, not ediff specific. Thanks. --=-=-=--
