nah..i camped it yesterday from 7pm CST and it popped at 7:07am..thats about 12 hrs or so ^_^ had my bf PC camping one city, me one city and his bro PC the last city.
Depending on if your in DST or not that still could be in the window (I did hear 5pm once before too actually but assumed it was a fluke so that's my bad). But in anycase even then it's still only one hour difference and if the other part of what I said in the post holds true there still would have been a pop the next hour to give you the window of 6-9am/pm pst. I believe you over-camped for no reason and wasted a good 7 hours (Though you may not have wasted them if you were intelligent about how you camped them).
