Hello how may I help you? I have some questions about time zones. how can i help I would like to know how time zones work, like Pacific Standard Time and Eastern Standard Time. How they work? Correct. I can only calculate the times in different time zones What is the time in New York if it is currently 6 pm in Los Angeles? 9 pm So does that mean that PST is behind EST by 3 hours? EST is three hours ahead of PST Got it, thanks!
