[otrs] [bug?] Calendar's Today button not working

I am testing the calendar module and noticed that the "Today" button does not do anything useful. When Clicked - it just reloads the current calendar view (be it 5 day 7 day or 3 month view) IMHO it should be loading Today's appointments in the expanded format. I have OTRS 2.1.6 viewed the page with IE7 and FF 2.0.0.3 This problem can be viewed even on the demo system (2.1.7) http://demo.otrs.org/otrs/index.pl?Action=AgentCalendar Is it a bug that I should file or a "feature" that I do not understand? Thanks
