Please, check my site

I want to ask all of you to have a look on my site “” to see if everything is working all right. The thing is, that when I check my statistic of my page, I can see by almost all the visitors which have seen it, it shows up the time how long they’ve been on the website. Actually always shows up 0 minutes and seconds. It’s very wierd, so I just wanted some of you to look, what could be wrong. Anyway, is there any software which is able to check the function the sites, by the way? Thank you a lot for every help.
