Timezonecist 

When you assume another persons time-zone, you're timezonecist.

You: ''You're Eastern time. I'll see you at 8.''
Someone: ''Did you just assume my timezone? I'll have you know I'm Central not Eastern. You're Timezonecist!''

Timezonist

Not having consideration for other timezones in regards to hosting online events at specific times, meetings or just gaming. This means, you're timezonist

Eastern Time: "I'm hosting a meeting at 9pm EST, Can you come?"
GMT: Sorry mate, thats far to late for me, its in the middle of the bloody night! Any chance you could do it a bit earlier?"
Eastern Time: "NO, I wont do it earlier for you GMT boy."
GMT: Did you just not have consideration for my timezone? You're timezonist!"
