回答1:

Vaadin has a class called WebBrowser that provides useful information about the client (browser):

You can access the current WebBrowser instance for example as follows:

public class MyApplication extends Application {

    @Override
    public void init() {
        setMainWindow(new Window());

        ApplicationContext context = this.getContext();
        if (context instanceof WebApplicationContext) {
            WebBrowser webBrowser = ((WebApplicationContext) this.getContext()).getBrowser();

            Date now = webBrowser.getCurrentDate(); // Returns the current date and time on the browser
        }
    }
}

For more information about the WebBrowser class, see its JavaDocs.

Vaadin runs on server side, so everything you do there corresponds to the server itself. For your problem you can probably create a vaadin widget to get clients time(-zone) and pass it to the server.
