Listening to the talk, I don't think it was encrypted. They just said in early in the talk that it seemed encrypted due to high entropy. But later in the talk they decoded the payloads after they figured out the format.
But yeah, insecure time is a underrated attack vector.

As I understood it, that's likely weather data from a 3rd party (Meteocast) that they encrypt to protect their IP/subscription.
