What date exactly is shown for an extension in the Special:Version page?
I did install a new version of an extension and version number in column Version is changed now. But date is still and old date.
Run update.php.

update.php is just a maintenance script not a MediaWiki core update. If you have SSH access, it will take just a few seconds.
