Display something based on the publication date and cat

<?php if( in_category('certaincat') && (get_the_time('Y') > 2008) ) { /*show text*/ } ?>

get_the_time():

formatting date:

Thank you for your reply and help.

I kept getting a parse error with your code but a little copying and pasting from something else got me this

<?php
if ( in_category('catnamehere') && (get_the_time('Y') < 2008) ) {
echo 'text here';
} else {
echo '';
};
?>

There’s probably a more elegant way of doing it but it works.

Thanks again, your reply made all the difference.
