JayKidd -- Earlier, we had a report that the final match would be at 19:00 or 19:30 local time. Is the later time you are reporting -- 21:30 -- now official? (Trying not to sleep through it!)
21:30 was wrong, the CCTV website list the program starts at 22:15 local time, there will be a brief introduction before, I would say the live coverage will begin around 22:20. Again, pool has very low priority for CCTV, so be prepared to miss a couple of matches when the live coverage begin. And another ATP program is listed to start at 23:00pm, so you may not be able to see the end of the match either.
The reason I said 21:30 was, according to Joy's website
http://www.zs8q.com/forum.php?mod=viewthread&tid=127835&extra=page=1, the schedule page lists the final was set to begin at 21:40.
In last 3 days, 19:00 or 19:30 localtime was when the last round usually begin, however there is only one match (the final) left, and the only place you can watch it is CCTV channel 5. So in order to let more people watch it, the final match time is set very late.
CORRECTION:
The match will start at 21:40 as advistised on Joy's website, it will be streamed through the usual 4 websites listed, although the number of camera probably wil be limited. CCTV5 live coverage will start at 22:15, and may stop at 23:00.
