from my understanding jessica jones comes out on 20th but does that mean the 20th in the u.s or is it the 20th specific to whichever timezone you're in?

it's 8.00 p.m november 19th here in australia, so, will jj be available in here four-ish hours (when it's the 20th) or will it be out for us on the 21sf? (i assume it's the latter but i wanted to be sure)
