Setting Timeline Intervals

[yo]

Hello,
iam trying to change the time intervals, but it doesnt work. This code is not changing anything

public void onModuleLoad() {
        RootPanel rootPanel = RootPanel.get();
       
        CalendarSettings settings = new CalendarSettings();
        settings.setIntervalsPerHour(4);
       
        Calendar calendar = new Calendar();
        calendar.setSettings(settings);

        rootPanel.add(calendar, 142, 117);


Any suggestions how to fix this?

Thx
