Toro,

Sorry, I think your calculation is off by one.

is really 9:00 pm for you minus 3 hours

is a bit confusing.

Look at it like this:
Arizona is Mountain Time Zone. They never change to Daylight time. Therefore all summer they are 3 hours behind EDT (which is Stars Lobby Time in the summer), and all winter, when we change our clocks back, they are 2 hours behind EST (which is Stars Lobby Time all winter).

But you did get the right answer:

The 20:00 = 8:00PM EST game will be at 6:00PM MST in Arizona.
