- I recently posted a question about file locking and received a reply
- from Walter Hunt. I tried to reply by email but have been unsuccessful.
- The message is of general interest, so I am posting it.

- Neafsey's reply:
-
- According to the original (Japanese authors) installation instructions
- for demacs, you are supposed to SET TZ=XST-9, where XST is your time
- zone (CST for me). This statement can be put in an emacs.bat file
- that runs everytime you start demacs or in your config.sys file.
-
- When you do this, demacs keeps the right time, as you can
- demonstrate if you type (current-time-string) in a buffer, put point
- immediately after it, and then type C-x C-e. Unfortunately, although
- the time is right, when you try to save files, demacs starts telling
- you it can't because of "userlock" or something like that. You can
- work around this by deleting the actual file using dired and then save
- the buffer again. However, this gets annoying.
-
- You can "solve" the problem by changing SET TZ=XST-9 to SET TZ=XST,
- as mentioned in the demacs FAQ file and in the American installation
- instructions. Now demacs has no trouble saving files because of
- userlock. However, the time is now wrong, as you will see by doing
- the (current-time-string) thing again. It actually turns out to be
- Japanese time (if it's really 6:00 AM your time, demacs says it's 8:00
- PM). When demacs reaches midnight, the day changes to tomorrow. For
- most people this is OK, a small but annoying quirk. However, it sure
- would be nice to have it keep correct time and date, so that files are
- labeled with the right timestamp and calendar programs would work
- right.
-
- That's it, as far as I understand it. I'd like to fix it, but I
- can live with it.
-
- Hope this helps you. Let me know if you figure it out.
