NOTE.- This is a very tricky bug, which does not happen on my local moodle test sites (Windows XP, Apache, etc.) but happens on 2 distant sites: my university and my personal test site at http://rezeau.info/moodle where it can be seen logging in as moodler, password moodler, go to course Dates bug Test.

The attached table screen shot sums up the problem, which only happens with certain settings, including unfortunately the one I have to use for my English courses on an otherwise all French moodle site (my university).
Site language = French; User's Preferred language = French; Site front page language choice = default (French); Course forced language = English. RESULT: dates within the course are displayed in French, not English.
The same bug happens with an all German moodle site and Course forced language = English.
However, there is no such bug with Spanish, and there is no such bug in a **reverse** situation where you have Site language = English; User's Preferred language = English; Site front page language choice = default (English); Course forced language = French.

There is a workaround, selecting on the site's front page from the languages dropdown list the course's forced language as the language option for navigating the site. But this is not a valid option for users who have several courses on the same moodle site with different Force language settings.

I am puzzled why this bug should happen a) with some language combinations and not with others and b) why it should happen on some platforms and not on others...
