People like to complain that the Tick unfairly benefits some players based on Time Zone; if the tick happens just as you're able to get on, you can take advantage of the new prices/stocks/etc, while other players are left out in the cold.
So, simple solution; make the tick happen 4 hours later every day. That means that each week, every time zone gets an opportunity to take advantage of the tick, AND the cycle would slowly roll back, so the day each time zone got wouldn't be the same every week. That way you don't get unfair advantage to the time zone that happens to get their ideal time on a Saturday or Friday night or whatever.
