setlocale() only works with xx_XX lang strings

[Oliver Schulze L.]

Hi,
I have
imp 2.2.6
horde 1.2.6
php-4.0.4pl1-7
redhat 7.0

and I'm using the spanish language and the setlocale() function of php 
only works
if the language string is in the form: xx_XX
In the spanish case this is: es_ES
In IMP, the language string is only 'es' and not 'es_ES' and this
make setlocale() to fail setting the locale.

I solved the problem setting setlocale manually in:
/imp/lib/postconf.php3

Is this normal behavior of the setlocale() function?

To check this, login in IMP in a language diferent than English
and check the date strings after using this line in your defaults.php3:
$default->date_format = '%d/%b/%y';

Thanks
Oliver
