This months posts as startpage – revived!

Hey everyone,

I wanted to revive this simple script by Beel, which will show only posts from the most recent month on the main page.

<?php if (date(m) == the_time(m,0)) { ?>
and at the end
<?php } ?>

Now, it works fine…with one exception. The page displays nothing when visiting a monthly archive (m=200501, for example). Is there a way to make this code “active” only if $m is not set? This would then display monthly archives, as well as displaying only the latest months postings on the main page.
