Hello how may I help you? I have a question about time zones I can help you with that. How do they work? Unfortunately, I am only able to calculate the times in different time zones, not provide information on how they work. What time zone is California in? California is in the pacific time zone. Whatis the time difference between LA and New York? The difference would be 3 hours. Thank you for the info No problem. Can I help you with anything else? That is it
