If you want to get an event every 10s during which you can update the content of the page, consider a repeating timer: https://www.zkoss.org/wiki/ZKComponentReference/Essential_Components/Timer

Timer will generate an "onTimer" event on a period defined by the "delay" attribute. Remember to set both delay and repeats if you want an ongoing event: delay="10000" repeats="true" -> every 10s

Alternatively, you can consider server-push: https://www.zkoss.org/wiki/ZKDeveloper'sReference/Server_Push/Configuration CE edition has polling server-push available, which enables you to trigger updates from server-side. In the case you described, I'd still go with timer since you want to do periodic updates though. Server push use case is more along the line of "I want to update the client after an unknown period of time, or when something happens at server side."
