Hello how may I help you? I have a question about time zones. Sure! What is your question? How in the heck are they supposed to work I can only calculate time zones for you. I cannot tell you how they work. What?! Aw, man. Well, can you calculate what time it would be in NYC when it's 8:00 PM in Chicago? I cannot provide information about New York, sorry. Wait, that doesn't make sense. How can you say that you cannot tell me how they work, then tell me you can only calculate time zones, then can't calculate NYC? Confusing! I'm sorry, it would be 5pm in New York when it is 8pm in Chicago. What the- Isn't NYC an hour ahead? I'm confusseeeddd! No New York City is 3 hours behind based on the world map. I hope this helps!
