Looks like you do not have a crontab file set up or its corrupted.
try crontab -l to list the crontab file...
Still nothing...

use the crontab -e to start your new crontab file
enter the commands then save it.

3:00am each day would be
00 3 * * * /my/script/to/run > /dev/null 2>&1
do a man on crontab or cron for info

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
