This is why someone suggested 2 of them with 12 hour differences. That way everyone can get to do it, but even in that case it could make a lot of difficulty around the world. like think about having it at 3 pm when you are working and 3 am at the night when you are sleeping, that could still very well happen too.

This is why it's hard to pick a system, and some places have tiny versions per hour type of deal, which doesn't get the same attention that is why blackjack.fun might be doing the correct version. Sure I am usually asleep by that time when they do it, but that doesn't change the fact that they can't end up with something changing and ruining everything. If they do that then they are going to end up with a lot of trouble.
