How to change the code to fire every 30 seconds?

This should work.

<!--Begin Real Time on Site and Bounce Rate -->
<script>
var _gaq = _gaq || [];
(function (tos) {
window.total_time = 0;
window.setInterval(function () {
total_time += 10;
tos = (function (t) {
return t[0] == 50 ? (parseInt(t[1]) + 1) + ':00' : (t[1] || '0') + ':' + (parseInt(t[0]) + 10);
})(tos.split(':').reverse());
if (window.total_time <= 300) {
window.pageTracker ? pageTracker._trackEvent('Time', 'Log', tos) : _gaq.push(['_trackEvent', 'Time', 'Log', tos]);
}
}, 30000);
})('00');
</script>
<!--End Real Time on Site and Bounce Rate -->

Thanks for the reply.

I seem to have gotten it to work with the below code. I really just needed to see if readers where on the page for longer than 30 seconds. The 10 second events was overwhelming my event report. I couldn’t get any good data out of it in the events section.

Although its not really the plugin’s intended purpose, its been s great starting point!

return t[0] == 30 ? (parseInt(t[1]) + 1) + ':00' : (t[1] || '0') + ':' + (parseInt(t[0]) + 30);
})(tos.split(':').reverse());
if (window.total_time <= 30) {
window.pageTracker ? pageTracker._trackEvent('reading_blog', 'Log', '30+_second_blog_reading') : _gaq.push(['_trackEvent', 'reading_blog', 'Log', '30+_second_blog_reading']);
}
}, 30000);
})('00');
