system alerts time to short

Hello,
i want to change the time that system alets displaying at the to of the sceen.
is it possible to do that?

Thanks,

I'm afraid its a Joomla core thing. Perhaps there are plugins that allow to control its time.

Thanks for reply,

This message at the top of the page i mean.
I tried to change the template and the message didnt hide after 3-4 second with the other template.

Thanks

I found it,
gk_shop_and_buy/js/gk.scripts.js

if(jQuery('#system-message-container').length != 0){
jQuery('#system-message-container').each(function(i, element){
(function() {
jQuery(element).fadeOut('slow');
}).delay(50000);
});
}

Oh, so actually this was a template generated message - you were faster... I'm glad you could solve it out.
Please let me know if you would have any additional questions regarding this topic.
