If we're going by tomorrow and factoring in your time, I would say from 9:00 to 8:00 (or 20:00). Ideally, I would say 4 PM/16:00. But if you're looking to get it done tonight, I got an extra hour to spare.
Hey, I'm on GMT -4 (EST). I can play at around 4 PM today up until 10 PM. If you won't be available during that time window, I can go at any point from 12 PM to 10 PM.
Hey, I won't be able to play today, but I can go at any point tomorrow between 12 PM to 10 PM. I'm also on GMT -4. Ideally, I think 4 PM would be a good time, but that's up to you.
