I don't see what is so hard about this.
If you want to figure out EST/EDT, click on the USA link on playonline.com. The USA portion always posts stuff in PST/PDT. PST/PDT is ALWAYS 3 hours ahead of EST/EDT. So just add 3 hours to the PST/PDT times, and you get your EST/EDT times.
No need to convert GMT or GMT+1, especially coming from a company that doesn't even take into account GMT+1, as Hwang said before.
You people are seriously making this harder than it is. PST + 3 = EST.
