NBC has paid for swimming and gymnastics to be shown primetime in north america.
Beijing is 14 hours ahead of Calgary.

If you click on aquatics-swimming for example you will see something like:
10:00-10:07 Men's 400m Individual Medley Final
So Phelps will be racing in the morning over there.
I've also calculated the men's 100m final to be Saturday Aug 16 at 8:30am Calgary time.

I dont think there will be any incidents.
I predict 13 medals for Canada.
