Please do not make us lock the thread over this. Constructive feedback about time zones are welcome of course, but the discussion has been had numerous times and can only be repeated so many times before it can feel overly repetitive to other users. Also, the same applies in reverse, so please do not ridicule other users for providing said feedback which they are entitled to say. (even if I may not agree!)
Note that time zones are always considered when setting times and this time was already picked in careful consideration of that. I personally do not consider 11PM or 12AM to be unreasonable when it could be much later. 6PM EDT is actually a careful compromise between offering a time later in the day for the west coast of North America while still considering Europe. A better time for everyone in North America would actually be 9PM EDT, but we picked an earlier time intentionally to keep Europe in mind.
