@rancid Hey there! Sorry it took me so long to respond. We just finalized our times for the events. Please note that these times are subject to change in the future. Asia/Australia cups are slated for the times listed below:
4:00PM SGT (Singapore)
6:00PM AEST (Australia) THIS TIME IS WRONG
12:00AM PST (Los Angeles)
3:00AM EST (New York)
9:00AM CET (Europe)
Because it is only a 8 team single elimination bo3, each round is scheduled to take an absolute maximum of 1 hour 30 minutes. Multiply that by 3 (8 teams in round 1, 4 teams in round 2, 2 teams in round 3), it will take a maximum of 4.5 hours. This is in a worst case scenario where in all three rounds, all matches scores’ are 2-1.
The main reason we scheduled it for the afternoon is because the majority of our staff members are located in North America. For me personally, I’m going to have to be up from 11pm to 4am to work the event. However, none of these times are written in stone yet. We still can change things if we need to. We’ll talk to the teams after the event to see if the time needs to change or if we’re ok.
Finally, as @wolvie said, the Christmas Cup only ran for 3 hours. We were really lucky with that one as, I believe, all matches ended with a 2-0 score. Plan on the timing being between 3 and 4.5 hours. If you have any more questions, feel free to let me know! 
Edit: We’ve got a meeting tomorrow. I’ll be sure to bring this up. I’d really like you to be able to participate, and I really don’t want to shut the door on you guys. I’ll see what we can do!
Edit 2: I screwed up. The Australia time listed there is incorrect. It starts at 8pm AEDT. Unfortunately, finding a happy medium between time zones is very tricky. We’ll see if we can work something out.
