Time Zone Population

Guess the time zone based on the given population. Enter the time offset from UTC. Since JetPunk doesn't recognize punctuation, enter "UTC6" for "+6" and "6" for "-6". Yes this is cumbersome, but someday JetPunk will enable multiple choice for user-created quizzes and I'll update to that style. Don't forget about the .5s and .75s!
