setup a cron job to be executed on the first day of every month:
0 1 1 * *  /PATH/update-crontab > /dev/null 2>&1

the script gets the last second day of the month, and then updates root crontab, e.g.:

typeset -i d; for i in `cal | tail -1`; done; d=$i; d=$d-1; echo $d
grep -v LAST_SECOND_DAY_JOB /var/spool/cron/root > /tmp/tmpfiles111
cp /tmp/tmpfiles111  /var/spool/cron/root
echo "0 1 $d * * LAST_SECOND_DAY_JOB" >>  /var/spool/cron/root
rm /tmp/tmpfiles111
