Question about Cody's timeline... (Worm spoilers) How long is the time between him being given to Accord, and him fighting Behemoth with the Yangban?

The story says that he's been with the Yangban for over a year. But the moment he was given to Accord is the same moment the Travellers were first called by Coil. The Travellers' meeting Coil happens around the time of the villains' meeting to discuss Lung, which is a meeting Skitter attends.

Let's assume the Travellers didn't take long to meet Coil after his call to them. The time between Skitter being present at that meeting, and her fighting Behemoth, is decidedly less than a year --- it's about half a year or less. So how could Cody have bene with the Yangban for over a year at this point?
