This 3 key's are for the DatePicker, if the same rule is applied for the 3 then you can echange for each language, the days month and years.
but all 3 must have the same format in the same order then the Database and display have always the good string.
If it's not respected then database save are false.
problem is Joomla 1.5 use old syntax,datepicker javascript another and Joomla1.6+ use PHP directly.
But on thinking, i think i writer a simplier solution next
