Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
This is a minor issue.
Middle-endian ("US style") dates confuse me.
I set TIME_STYLE=long-iso so I won't have to deal with them.
This works for GNU ls and GNU tar:
bash5$ touch x; ls -l x; tar cf x.tar x; tar tvf x.tar
-rw-r--r-- 1 twb twb 0 2020-05-12 14:32 x
-rw-r--r-- twb/twb 0 2020-05-12 14:32 x
This doesn't work for tar-mode, because
it processes tarballs using native elisp:
bash5$ emacs -Q -eval '(setq-default tar-mode-show-date t)' x.tar
-rw-r--r-- twb/twb 0 May 12 14:33 2020 x
The responsible code appears to be tar-clip-time-string which appears to
munge the output of CURRENT-TIME-STRING:
(defun tar-clip-time-string (time)
(let ((str (current-time-string time)))
(concat " " (substring str 4 16) (format-time-string " %Y" time))))
Where CURRENT-TIME-STRING appears to be hard-coded to a format.
That format matches neither
GNU "date --rfc-email" (little-endian) nor
GNU "date --rfc-3339=seconds" (big-endian).
Surely emacs already supports locale-appropriate timestamps somewhere?
Please hook up tar-mode to use that code.
PS: see also "locale -k date_fmt", which these days seems to be the same
for me (en_AU.UTF-8) and the default (C.UTF-8), hence why I use TIME_STYLE.

This is already fixed in what will become Emacs 27.1: there we display
the date in the yy-mm-dd format. You can find the latest pretest of
Emacs 27.1 on alpha.gnu.org.
Thanks.

Since this is already fixed, I'm closing this bug report now.
Please reopen the bug or open a new one if you can still reproduce this
on Emacs 27.1 or later.
