Wow, we hear your feedback loud and clear! The feature you're all asking for is per-event time zones, which is a really great idea. In fact, we've been discussing and working on that exact feature, based on much of your feedback. However, dealing with time zones at the event level can be tricky, and implementing the best solution does take some time. In the meantime, you can try some of the time zone features that are currently available in the product (in my previous post). These features may be a great fit for some of you, and others, not so much -- which is why we will always listen to what you have to say.
Adding time zones to individual events is really important -- to you and to us! Thanks for telling us what you think and for being patient as we work on this feature :)
