[support] bit of php code in a block - how?

[Daniel]

Hi everyone!

I'm trying to put a little one-line date string on my site (eg.: 2007. 
April 16 (Monday)). The most quick and easiest way I thought was to 
create a new block (with admin/build/block) and put this code in it:
<?php
echo date("Y. F j. (l)");
?>

Then add this block to my site.

But when loading the page I just get the code displayed and not 
executed. I have an Input format which allows PHP code and is available 
to nobody (so I can use it only with uid==1), and I've added the block 
content with this filter.
Can't see what is the problem :\

Please comment, thank you!

ps.: If there is a feature already in drupal which does this, that would 
be even better :)

Daniel
