Somehow my deadlines have mysteriously morphed without anyone bothering to tell me.

I'm working on [insert secret project here], and was supposed to deliver a rough usage model by Friday and the first-cut at a spec by December 16th. Somehow, this has morphed into delivering an implementation tomorrow.

Um... huh?

What's worse is that my customers are not internal. Cadence is expecting this, well, now-ish.

Who's responsible for this fiasco? I'd like to choke the living daylights out of him.
