Of course there are issues with the semantics of date (let alone with date formatting). Are you asking for web pages created on a certain date, or containing information about that date? Are you specifying a date range, or are you looking for a specific date?
What's to stop these tools being used to ping a date registry when calendar information is posted in a public space?
An online counterpart to the atomic clock?
So, Apple, Microsoft, Technorati, Google, FAST, Yahoo! and MSN, get together and give us time-based search. The UI doesn't really matter (though a calendar grid would work really well for drill down), as long as we can sort results by date...
