Well, you know how the world is round, right? The world is apparently 24,000 miles or so in circumference and spins around 1,000 miles an hour on its axis. That means it does a complete rotation every 24 hours or so. Thus, each 1,000 miles is broken up into a time zones that add an hour to the previous zone as a person goes east (except those weird third world countries where they have a 30 minute time zone). Any how, if it is 7 pm on the pacific coast, that means that those in the central coast region (roughly 2,000 miles further east) would add 2 extra hours to the pacific coast time. So you're looking at 9 pm. Oh, if you live in AZ, HI, or IN, your state does not practice the day light savings time thing, that may impact your caculation.

with levity,
