Hello how may I help you? So I'm confused about something. How can I help you today? I'd like to try to help clear this up for you I have a flight that takes off a 5 PM, but it lands at 4 PM the same day. How is that possible? I can only calculate times in different time zones, so if you have that, I can maybe help you It's from Chicago to Los Angeles. What time is it in Los Angeles now? Los Angeles is Pacific Standard Time, Chicago is Central, which is 2 hours ahead of Los Angeles How do time zones work? I'm sorry, I can not provide information on how they work Okay, well thanks for the information. I couldn't figure out if I was time traveling or something. I understand and hope I haven't confused you further. Please come back if you have any further queries. Will do. Thanks!
