via radio link, the electronic legend in the background displays the time as "GMT 15:11".
In the next scene, when Garthe tells Devon and April that he's going to overload the
electrical circuitry in the mansion, he starts by saying "Good afternoon . . . ".

Surely if GMT is 15:11, then the time on the US west coast would be 07:11. In that
case, shouldn't Garth have actually said "Good Morning . . . ". Or, with Garthe being
such a nasty so and so, was he trying to fool them into thinking it was afternoon?
