Could it have nothing to do with RTL at all and just be different date/time conventions like in English (en_US) the date format is mm/jj/aaa but in French (at least fr_FR) it's jj/mm/aaaa?
Except that it also happens with custom layouts (e.g. "12 hh" instead of "hh 12").
Note sure why it would be specific to v6 though. Maybe older versions did not always take the date/time convention into account?
Probably, yeah.
