The last time I used my adwords account, the daily budget wasn't a set thing. If you received a bunch of clicks one day and went over your budget, your campaign would be adjusted automatically to stay under budget. If you stayed under budget for a day or two, your ad positions would be maxed out, based on bid amount and popularity, to bring you back up to budget (or as close as the keywords allow).
Adsense stats don't update real time. Even if you're using an independent tracking script and/or channels to track clicks, it would be difficult to determine when the high paying clicks were coming in.
Tracking is not easy. Not even if you set the date in the script to match the pacific time zone, the days differ by a small percentage. And I know for sure that my site is hardly visited from midnight to 5:00AM because my traffic is 90% North American.
I also don't think it matters so much the time of the day as to when your target demographic has access to a computer. In my case, it seems to be office workers dreaming of independence.

Yeah, those guys drop by my site a lot too.
Usually between 3 and 5 in the afternoon. >;->
This is also my target audience and I can report that 14.00-18.00 (UTC) is the prime time for our business site.
I was shocked to find out that one of my sites visitors is lowest during business hours. I looked at the stats for a long time trying to figure it out. I filtered out anything that could be a spider it was over a month period. We are going after people that don't have jobs. The topic is very US.
I get the most traffic from 9-12 in the morning and then it increases again from 8-10 in the afternoon. So I guess my visitors come from both employed and unemployed categories :-)
Zeb, I've seen the same thing. After checking my stats mid- or late-morning, I've often thought how great I'd do if the same rate per click would hold up for the rest of the day, but it usually doesn't.
My peak hour (for pageviews) is 1PM Eastern. My main peak is 1-4PM, although it's still very high during office hours (10AM to 6PM).
I find it hard to correlate AdSense earnings to a particular period, due to AdSense's overall reporting lag and tendancy to update different statistics at different times.
