The Nighttime Transmission

I've been reading one of the branch manuals for the Canadian version of Wells Fargo and they keep mentioning a "Nighttime Transmission" but they never really explain what it is. They'll say things like "The nighttime transmisson will always include a statement of progress." and "The nighttime transmission sent one day cannot be requested on the following day."

I'm starting to think that the nighttime transmission is a communication with the homeworld, keeping them informed on the status of the infiltration and terraforming of the human world.

If Wells Fargo were being run by space aliens, I wouldn't really be surprised. In fact, it might explain a few things.
