best way to get a 1-second timer-tick?

I have written a module to implement sFlow in nginx (nginx-sflow-module.googlecode.com). I'm simulating a 1-second timer-tick by assuming that the request handler will be called at least once per second. That's probably a safe assumption for any server that would care about sFlow monitoring, but I expect there's a better way...
I tried asking for a timer callback like this:
ngx_event_t *ev = ngx_pcalloc(pool, sizeof(ngx_event_t));
ev->hander = ngx_http_sflow_tick_event_hander;
but (like most russian girls) the event never called me back. It looks like I might have to hang this on a file-descriptor somehow, but that's where I'm getting lost. Any pointers would be most appreciated.
