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.
My best times are Wed and Thursday evenings but they correlate poorly with your time.
Otherwise i can do Thursday or Friday morning (8:30am, which is 4:30pm the day before in your time, I need to ensure you come online in time as it's just before uni), Saturday afternoon (I would prefer not to do this), or my Monday any time (easiest for me but we may need to ask Stratos for an extension).
If you can do 4:30 PM local I usually stay up until 12 AM anyway, but otherwise the best option sounds like Thurs/Fri morning for me, unfortunately. If these don't sound good we can go ahead and request an extension.
