Tick-tock

White House press secretary Robert Gibbs responded yesterday to a reporter's request for when the Administration knew something, and when they knew, it by saying "I don't have a particular tick-tock in front of me. And, obviously, I was not involved in all of those conversations."

That's a new one on me, and I expect to hear it a lot where I would have heard "time frame" in the past.

Journalism talk. I guess it means chronology or maybe all the steps/events leading up to something.
