Update Error

When I am in the backend of Joomla and I try to update hikashop from the extension menu I run into message that says:

Fatal error: Maximum execution time of 60 seconds exceeded in /htdocs/libraries/joomla/filesystem/archive/zip.php on line 320

Anyone know what is going on?

Joomla takes too much time to unzip the package because your server is too slow.
You should try the install via FTP:
