Hello how may I help you? Can you help me with time zones? Yes, I can help with that. How do time zones work? I am sorry, I can only provide information on different time zones, not how they work. Can you give me the difference of times between two cities? I am sorry,I can only tell the time in different zones. Would you be able to tell me the time difference between EST and PST? If it is 9pm in EST, it is 6pm in PST. Awesome, thanks for the information! Anything else?
