There are two places for cache times. One you went to already the other is at
» Control Panel » Portal Settings .
I would put them both at the same time.
Also if your site has very little traffic it may not update to quickly. I just tried your site and it updates you just have to select the who's on line a couple of times till the cache times out. If you had a little more activity you would see it update more frequently as to what you have it set for.
I had the same question at
