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.
13:30 GMT should be like 8am my time, I'm really not a morning person. I could play after 12pm gmt-5 (17:00 GMT), or if that doesn't work I can try playing an hour earlier
im afraid 17:00 and 16:00 both don't work for me since I always start to cook and ofc eat starting at 16:00 but 15:30 works for me if that also works for you
