Yes and no to the original question. I basically don't pay much attention to time zones, with two exceptions: friday and saturday evening/night. I live in Europe, and I do my damnest to be able to play those two times. My time, say, 18:00-22:00 pm is a great time due to people playing drunk. Great time to make money. Then again, those are times for the worst bad beats...
Last friday I was playing again, and on one of the tables there was a player who was clearly drunk and I had been following him for a while. The game was NL100 and I got dealt AA in UTG. I open to $4, a short-stack player in MP pushes all-in for $12.50 and button calls. I re-raise to $49, button thinks for a while and pushes all-in for $112 or so. I call and he turns over A9s...
What do you know, a 9 on the flop and a second one on the river. Like that's not enough, the same guy against me, I had opened again $4 with JJ and he called. The flop was 48J, two diamonds. I bet pot with my top set, and he raises big, I go all-in, he insta calls with K6 of diamonds and hits his flush on the turn and no help for me.
I seriously couldn't do more than laugh, despite losing two buy-ins, I found that hilarious. So let that be a reminder to all about playing against drunken people... It's not always "give me your money, donkey", it can also be "stop taking my money, donkey".
