Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
would you prefer playing at your morning or during your evening? during your evening i would suggest 10pm gmt+12 but i can do 9pm your time as well on sunday. how does that sound to you?
I'd much rather play in the morning tbh if that isnt too late for you. Any time after 8:30am should be good, on Saturday or Sunday. So that's 11:30pm onwards for you.
