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.
Can you do like 10am(/7pm my time) sunday or is that too early? Otherwise is 11am your time is fine too but I would like to not play later than that if possible.
10 AM my time on Sunday is actually perfect. I do have a different series going on at 9 AM, so it could run a little late, but otherwise that timing is great.
