IF it's running under anacron, it doesn't run at 7:30 - it works like you do
and runs 'delay' minutes after you boot up (or at least, after anacron
starts).

However, anacron isn't running if the machine is turned on - so then you
need to either remove updatedb from cron.daily and create an entry
explicitly for it in /etc/crontab (with whatever crontab editor is
appropriate on your system - I use kcron, it's better not to do it by
hand), or modify /etc/crontab to do runparts on cron.daily at 3:30 instead
of 7:30 (just change the 7 to a 3) - then _all_ of your cron.daily jobs run
at the same time.
