Wether it’s Blizzcon or some other important event, you always seem to mess something up by communicating wrong time/date for zones that aren’t US (because it’s so hard to get right 
) . Now with all stars you did it again.
I’m in Europe and it is currently wednesday here. On tuesday (yesterday) I received an e-mail regarding the upcoming All Stars event. Among other things it says “Tune in live on Twitch Wednesday and Thursday at 3 am CEST to find out” (CEST is a European timezone). So yesterday when it was still tuesday, it meant that after the clock passed 00:00, it became wednesday and only 3 hours till the event. Because wednesday 3AM, means wednesday at 03:00 in the morning. But the event didn’t roll. When you look at the schedule, it also says wednesday 3AM

(do note the: “All times are in your local time” line)
Could you at least change your website because what you did mean was this:
Thursday at 3AM & Friday at 3AM (03:00 for us normal people 
)
