Hello how may I help you? I have a question! Great! What is your question? How do time zones work? Sorry, I can only calculate times in different time zones but cannot provide information on how they work Okay, that's no issue. If it was 10:00 PM in Iceland, what time would it be in San Diego? The time would be 3:PM in San Diego if it was 10 PM in Iceland Thank you very much for the help! You're welcome, anything else I can help you with?? That's all for today! Have a good day!
