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.
Ok, so I am GMT -5 so you are always 2 hours behind me, mmm... does 1 pm gmt -5 on Sunday works for you? Let me know and we shall see how to make it work. Worse comes to worse I can stay until late on Sunday and we can play at 9 pm gmt -7. Do tell.
Lets go with the backup time now, something will come up between my 1 pm and moving forward until night so if there are no issues we can play at your 9 pm. Hopefully it will be okay
