k ubuntu - finding out command execution source (cron?)

I got an kubuntu desktop box. This box is neatly set up and suits all my needs.

However: the previous owner had the box shutdown at 23:30 (11pm 30 Mins) every day in order to save electric power.

Syslog tells me:

23:30:02 kubuntu-871263 CRON[17372]: (root) CMD (^I/sbin/poweroff)

I therefore investigated

crontab -l

17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 22 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 22 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 22 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

for root and all users.

I can't find the origin of the poweroff command. Any ideas where the command at 23:30 is originating from.

PS I can't ask the previous owner.

I found a crontab file in /etc that is the systemwide crontab (/etc/crontab) . This file contained the poweroff command at 23:30.
