What time is the launch on Jan. 30?

Does anyone know the actual time they are starting the event? Specifically is it during market hours?

There's another thread that notes the times people have seen in their invites. It's 8:30 EST for Toronto/NY, and will occur simultaneously in the other time zones where there are events. The TSX and NASDAQ open, I think, at 9:30, and the event is a few hours long, so there's definitely portions that will occur during market hours.
