Can you play in the Europe timezone and get the same results as in the US time zone

Hello,

I`m from Europe I want to play poker. But I have a job. I don`t really have to anything at my job but supervise which means that I can play poker at work.

My only question is can I play in the normal Europe timezone as many games as I would if it were night (or the American Timezone) or I can earn significantly more on the American Timezone because there are more Americans with big pockets that play for fun and are (fishes) and you can beat them a lot more easy?

Thank you
