Thanks to Adam Lebow for sending in the following:
The Score, home of WWE Smackdown in Canada has its upcoming schedule for WWE Smackdown on it's website and it is rather interesting. Tonights Smackdown, as usual, will air at 7 pm et with an 11 pm et replay (and another replay 2 days later (Aug 27) and 2 am et)). However, starting next week, when Smackdown moves to Fridays in the USA on UPN (and changes its name to Friday Night Smackdown), The Score has Smackdown listed for the following times. Smackdown will CONTINUE to air on Thursdays in Canada, moving back to its former 8 pm et timeslot, with replays now at midnight (Sept 2nd, Friday) as well on Friday at 3:30 pm et.
The same time slot is scheduled for the following week. As a result, it appears as if Smackdown will air a day earlier for it's Canadian audience (8 pm et Thursday) compared to the US Audience on UPN (8 pm et Friday).
