Org heavily depends on parse-time.el. Providing a defcustom in Org that is tied to parse-time.el at the same time is not trivial. Thanks, -- Bastien

Can you expand a bit more on this? The thread is not completely visible in google groups, dunno why. Please read at gnu.emacs.gnus with a newsreader. The problem was that the user replaced the English names with German names - instead of adding them to the lists. This broke Gnus. Currently, `parse-time-months' and `parse-time-weekdays' are internal variables with no docstring. Seems they are not intended to be changed by the user. Other packages may rely on the fact that the default values aren't changed. If they are supposed to be configured by the user, they should get a documented defcustom. At least, the documentation in the org manual _must_ be improved, so that the user is enabled to do the right thing without breaking anything else. > > BTW1: maybe a better solution would be to define own variables for > > this purpose in org, instead of letting users change variables in > > parse-time.el. > > Org heavily depends on parse-time.el.

You could just write a function `org-parse-time-string' that binds `parse-time-months' and `parse-time-weekdays' accordingly and calls `parse-time-string'. Then you would just need to call this new function from org code. Regards, Michael.
Hi Michael, I removed the part of `org-read-date' docstring about `parse-time-weekdays' and `parse-time-months'. You're right that this can lead too errors.

Org relies on `parse-time-string' through `org-read-date', a core command of Org. Thanks, -- Bastien
