There ae 2 problematic times. The first is 6:25 without anacron
installed. The second is 7:35 with anacron installed. Anacron just runs
later thatn cron:

mrvn@frosties:~% cat /etc/cron.d/anacron 
30 7    * * *   root    test -x /etc/init.d/anacron && /usr/sbin/invoke-rc.d anacron start >/dev/null

and anacron waits 5 miutes before actualy running.
