Change the time that cron.daily is run

Hey, all -- I'm trying to figure out how to change the time that the scripts in cron.daily are run. Currently they're processed right around 2 AM, 2:05 I think. This seems to be the default for 9.3. For various reasons, I need some of them to run between 12:30 and 1 AM. It used to be possible to change the single line that controlled cron.daily (for example) in /etc/crontab. However, it seems that all of the scheduled scripts are now controlled by calling /usr/lib/cron/run-crons each hour. It's not clear to me where the config info comes from that tells run-crons on which hour to run the cron.daily scripts. Anyone have any pointers?
