Time Based File System

I was playing with Evernote. I am fascinated with the ability to search documents based upon time. One can see this functionality in Office 2003+, where grouping allows emails based upon today, a few days ago, last week, last month, etc. While one can do a search or sort, it would be nice to see a grouping of items, so one can see the result of "I thought I was working on x a week ago..." and easily look it up.

What if...

Baseball outfielders had baseball bats?

Infield hit is an out (or a base hit?), foul is a double, outfield hit is a triple, and a strike is a home run.
