set_cookie problem =/ ~ beginner

[eluser]cehennem[/eluser]
I am trying to set a cookie like this;

set_cookie('username', $this->input->post('user'), 10); // 10 secs for test

it doesn't work for me.

But when I try higher values such as 5000, 30000 etc, it works nice (not sure when it's going to be expired)

I haven't post the full code coz of that interesting issue. It doesn't accept my small number of seconds.

Can somebody tell me whats wrong?

My first ques would be that it has to do with a mismatch of the time on you local computer and on your server.

Let's say your server thinks the time is: 12:00:00, and set's a cookie with a 10 second time to live, and on you local PC the time at the same moment is set to 12:00:11, then the cookie will never exist ..
