Hello how may I help you? I need some help with time zones. Sure what would you like to know? I'm not sure how they work. When you travel west, do you gain an hour? I'm sorry. I can only calculate time zones. I don't provide information on how they work Well, do you know if I leave the Eastern Time Zone and fly to the Pacific Time Zone, do I gain or lose time? I have no idea. But if you give the the time in one location I can tell you what time it is in another location. If it is 5:00 PM in Eastern Time, what would it be in Pacific Time? It'll be 2:00 PM Pacific Time So I guess I lose time as I go west. Thanks. You're welcome!
