Hello how may I help you? How exactly are time zone created and how do they work? I just calculate differences of Time zones I don't know anything about how they're formed or created So you can't tell me why Idaho is two hours ahead of Hawaii then? No I can't and Idaho is 3 or 4 hours ahead of Hawaii depending on which part Oh cool to know. Can you tell me what the time difference between San Diego and NYC 3 hours Okay. then if it's noon in San Diego it's 3pm in NYC? That is correct Thanks Have a nice day!
