This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
Answer is every "few seconds" -- which comes from their site...
"Near the top of the page, the number of people currently on the site that these stats are for is displayed, updated every few seconds. Below that, a timeline shows visitor trends for the previous 24 hours. You can click on it to view specific ranges in history. Under the timeline, in the left column we'll show you a few of the most popular pages right now on your website, and how many people are on each page. Beside the list to the right is a map display where people are in the world. Clicking on the list or map takes you to a more detailed stats page."
