They might be using a time base with launch time being the start of the epoc. It depends on what the on-board computer has to do. If all it needs to know is that after N seconds of burn it should shut off the engines and coast, it really doesn't care if that is 10:30am EST or 23:40 GMT. An Ada.Calendar package that required UTC for its implementation might just be the proverbial Brick S*** House in this application, which if this application required a validated compiler might preclude Ada from playing in that game. Better that a more sophisticated time package be included as some kind of annex or optional package. That's why I suggested that it might make a good candidate for a standard component library.
