Hello how may I help you? I have some time zone questions Alright what's your question? How do they work? I'm actually not programmed to help with that. I can only calculate the times in different zones. Would you like me to calculate a time for you? Well how many time zones are there? There are 24 time zones. So how do they decide which ones are where and how do they decide which one starts and 0:00? I'm not programmed to help with that! Sorry Okay thanks anyway No problem. Did you have any other questions?
