How to show users online within past 15 minutes

In my social app I have a repeating group always showing active users. I do this by having a date field in the Users Thing and a workflow thats runs every 30 secs that sets this field to the current time. My repeating group then searches for Users with this field containing a date not older than 30 secs. The workflow is put in the menu which is a reusable element. This way the action is performed on every page.
