Crontab and rkhunter Scheduling

I've got a system with Ubuntu 12.04 which has rkhunter installed. Currently the rkhunter daily scan script is located in /etc/cron.daily/rkhunter.

Every day at 7pm EST the rkhunter script is executed and the following is added to the /var/log/rkhunter.log file:

Info: Start date is Tue May 22 19:00:29 EDT 2012

However, here are the contents of my /etc/crontab file:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 3   * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

If I'm reading this correctly, it should be executing at 3:25am, not 7pm. I changed it from the default of 6:25 and nothing changed when the task actually executed.

The current output of date matches the local time on my machine. I also have restarted cron with sudo service cron restart since changing the crontab.

So, what am I missing here? Thanks!
