How to type check a Date object in flow?

Question

I have a function that takes a Date object as its paramater. I am not able to figure out how to annotate this.

function diffDate (start: any, end:any) {  //....  }

How do I type annotate start and end as Date objects?

Thanks loganfsmyth and Nikita for the comments. It works as expected.

function diffDate (start: Date, end: Date) {     // ...  }
