Hello how may I help you? Hi, I need help with time zones, can you help me out? I can do that for you. Can you explain to me how time zones work? I can only calculate time zones if they are different. Oh, I see. Can you tell me the time difference between New York and Miami? I don't know how that works but I can calculate that for you yes. Oh okay, thank you. First you need to select locations in different zones. Can you tell me the time difference between New York and Chicago? Yes, it is one hour. Okay, thank you! Welcome.
