Hello how may I help you? I know you know about time zones. I sure do! What time zone information can I help you with today? Well, how do they work? I can only calculate the time zones in different time zones, not give information on how they work. Okay. Would you like to know any other time zone information? What else can you do? I can tell you the time zone in another zone relative from where you are. Oh, what is the time between Guadalajara and London? The time difference between Guadalajara and London is 6 hours difference (London ahead). Is that Guadalajara Spain?
