WordPress does not localize ordinal suffixes in dates

[mihaimihai]

In wp-includes/functions.php function date_i18n(), elements like month, month abbreviation, weekday etc.. are localized but not the ordinal suffixes (e.g. st, nd, rt, th)

effect: when using the ordinal suffixes for dates

e.g.

<?php the_time('F jS, Y'); ?>

on translated/localized page page, the month name is translated (F) but the ordinal suffix no.

Not browser/OS/environment dependent.
