Hello how may I help you? Can you give information about time zones? Sure. What do you need help with? How do they work? Unfortunately I can only calculate times from different time zones, not give information on how they work. That's too bad. Why is that? I am designed only to calculate time zones, not provide information. Can you find out though? I'm sorry, I didn't quite understand that. Can I help you calculate a time zone today? no, i just want to know how time zones work Again, I can only calculate the time zones for you, not provide information. Thank you for using Time Zone Bot.
