Otherwise it's gonna be kinda difficult. 8h to 23h for me is 2h to 17h for you, if you have a preferred time in this frame do let me know.
I'm fine with doing my 2 am. I'd be down to do your 8-9 AM Sunday or your 10-11 pm Sunday if you can. If not lmk and I can see what I can do
8-9am Sunday (2-3am your time) should be fine, can always fallback to 22-23h (16-17h your time) if I miss or smt.
