China is 12 hours ahead of those of us who are in the Eastern time zone. If it’s 3:30 AM there (which is tomorrow, already, because they’re on the other side of the International Date Line), it’s 3:30 PM here.
This may help:

I get that part, it’s the NBC claiming things are live at 3:30 AM China time that had me confused.
