Thanks for the quick answer. But is that really true? Im sure Im not the only one setting up a multilang site with CB. Im really surprised that there is no solution yet especially because it is so easy to accomplish - just let the user select one of the Joomla native formats like DATE_FORMAT_LC and the problem is solved ...
I just cant torture my 5 different language users with the same date - they simply dont know what 12/11/13 means (or something similar). I definitely need a solution.
