This starts at 6 pm Mountain Time and 5 pm Pacific Time: a bad time in many households to be caught at the computer playing a game!
Not sure why such early times have been selected for what is a "west coast" shard that also serves folks in the mountain time zone, since we have no shards of our own to claim. I think you'd be much better off starting the events no earlier than perhaps 7:30 pm Pacific Time. That's just 10:30 pm for folks on the east coast....not too late for them since they are used to having to stay up until 11 pm to see the end of the prime time shows and then watching another half hour to catch the local newscast.
