Ten is currently studying as an Insei in Japan and after his first free lecture last week, he will give another free lecture on the 21/22 (depending on your time zone).
So i hope this link works for some time conversion
Otherwise well 9am on the 22nd in Japan is 0 UTC on the 22nd, which should be 8pm on June 21st for the US east coast.
