Calendar and World Events

I'd love to have a ticking clock so to speak where days pass and calendar days are marked off and seasons change. I can tell that Franz keeps track of time sort of under the hood. The other part of this is as a World Builder, I'd like tools to be able to tie into those calendar events. So, say 30 days past campaign start, without the characters going anywhere, they start hearing news about an invading army... 35 days later, a city is fallen, etc. This would allow us and Franz to simulate a much more lived in world where events happen and don't wait for the characters.
