Hello how may I help you? I'm interested in how time zones work Okay. What is it that you want to know? How far do you have to go before it changes time I'm sorry, I'm not designed to provide information on that. I can only tell you times in different timezones. So you don't know if time Jones change every 800 miles? Because I have a bet that they do I'm afraid I cannot confirm or deny that. Would you like to know times of neighboring time zones so that you can compare? Do you think Siri will know? I'm not sure I know Siri but it never hurts to ask. I got money on this and need an answer I'm sorry I can't help you more.
