The day is chunked into five pieces. Roughly 5 hours per chunk.

The idea is that this way, even if you exhaust one 5 hour period,
you'll still be able to serve the remaining 19.

Of course, the real reason is so when they start charging, this way
they'll be able to charge you for spike traffic that wouldn't
otherwise exceed your daily free quota.

Speaking of quotas, I'm really starting to wonder if there isn't
something really wrong about their calculation; I did a load benchmark
earlier, a simple ab2 -c 10 over a long period of time, after building
up the load. Everything was working great, until suddenly, after about
40k requests, a ton of requests started spewing the dreaded cpu
warnings. If I'd started a -c 100 or something then I'd understand it,
but this was the exact same load pattern over a long period of time,
and shouldn't result in any changes whatsoever on the google side of
things. A completely stable workload, but still app engine went funky
after a while and starting spewing the warnings that the requests
never trigger under normal circumstances. If a completely stable
workload like that will cause you to go over quota, there's no chance
in hell you'll ever get even close to saturating your alotted 5 hour
quotas.

(Sorry to derail your thread a little bit.)
