Here's the notice on lodestone about the time and date for the live letter to start.
Yet the countdown on the youtube link seems to be an hour early.We're pleased to announce that the next Letter from the Producer LIVE, Part V will take place on Friday, February 22, 2013 at 3:00AM (PST) / Friday, February 22, 2013 at 11:00AM (GMT)!

And indicates that the live letter will start at 2:00AM (PST)/ 10:00AM (GMT)
Can a dev please toss some light into this. I kinda want to know if I'll be able to see the live letter or not. Because if it starts an hour earlier, I'll miss it. Not a big deal considering I can see it later but seeing the thing live is always more enjoyable.
