PPVs have always been Live. It has always been at 5pm here. But watching RAW for the first 13 years or so, I always watched it at 9, an hour after it actually ended and the whole east coast was buzzing about what just happened. I would always stay off WWE.com and other websites on Mondays so nothing would be spoiled for me.
At different times over the years though, I would get RAW at 6pm when I had Direct TV or something like that. It has channels at their "regular" west coast times and then also it would have like USA East or whatever.
