Understanding Time Zones

I can't believe no one has ever thought of this before. Here's the plan, I call it
"The Time zone Exploit", I go watch a Dallas Cowboys home game. I call you in Los Vegas, tell you who won. Now you have two hours to place a huge bet on the winning team (because it's two hours earlier in Los Vegas) and just like that, we're rolling in dough. I will, of course, have to send a trusted Representative to accompany you. (I ain't no dummy!)
