Hello how may I help you? I have a question about time zones I can assist you with time zone information. What do you need to know? How do they work? I can calculate times in different time zones but I do not have information on how they work. Why is that? I am not programmed to give that information. I could however refer you to a better source. Why didn't they program That Into You? You will have to ask the programmers that. Okay thanks Thank you for using our service.
