WordPress MU

Somewhere the date format not use the main settings, and this is in English format.
In Hungary we're using Year. month. day. format.

Go into your admin panel.. Options > General

On the bottom half it has a "Date and Time" area where you can set the default date and time format.

Change the date format to: Y. F. j
or however you want it.. Y = year, F = month, j= date

Also remember that some themes override these settings.

Ok, I use the original temlates, and the archives links in months year format.
To work the Hungarian format, I must change some source code:
from this: $text = sprintf('%s %d', $wp_locale->get_month($arcresult->month), $arcresult->year);
to this: $text = sprintf('%d. %s', $arcresult->year, $wp_locale->get_month($arcresult->month,2));

AND
from this: $text = sprintf('%s %d', $wp_locale->get_month($arcresult->month), $arcresult->year);
to this: $text = sprintf('%d. %s', $arcresult->year, $wp_locale->get_month($arcresult->month,2));

in general-template.php

ps.: I use WPMU on Windows2003 server:

But I think this is not a windows specific problem, and same problem exist in the non-MU WP.

So, is there any solution?
