The event times displayed are based on your geographical location. We’ve kept it simple for everyone. What you see displayed as the event time is always correct, for you. If I’m in California and I set up a Wrath of the Machine raid for 6:00 pm but you are in New York you’ll see the event time displayed as 9:00 pm. Players will be online at the correct time no matter the location of the user. Do not worry about time zones.
