Google uses Oracle Calendar

With all the rumors about Google developing its own calendaring service, I've never read what calendar the company uses internally. This morning at OSCON, I got to ask Chris DiBona of Google. He says it's called Corporate Time and works with Oracle. (Later, I Googled Corporate Time and found it had been acquired by Oracle and renamed Oracle Calendar.) No Swampdrain rating to give here; just information to balance against rumor.
