Hello how may I help you? Hi, I was just wondering if you could tell me how time zones work? I can calculate the times in different time zones, but am unable to tell you how they work What are the different time zones? In the US, there's Atlantic, Eastern, Central, Mountain, Pacific, Alaskan, Hawaiian, Samoan Islands, and Chamorro What time is it in the Eastern time zone? It is currently 3:57 PM in the Eastern time zone How many hours ahead is the Eastern time zone from my time zone? Where are you located? I am in the Pacific time zone. Eastern time is 3 hours ahead Can you tell me what time zone is five hours ahead of me?
