Fights take place at 6pm local time of the event.
If you are in the East Coast that should be 10pm for LA/LV shows, GMT it is usually 2am.
PS - I had no idea that the times on the card were busted - I don't even know if they were always busted or just recently became broken.
This NEEDS to be fixed.
What you can do now is either ask a manager who's in that event when it's starting or note down the starting times of all locations. If you don't have them noted down, use event times from some other event in the same location as reference.
Like I'm using this as reference to know what time my LA event starts.
