Thanks for you reply.  I was looking at this again yesterday and
noticed the /etc/crontab file.

~>more /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file.
# This file also has a username field, that none of the other crontabs do.

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    run-parts --report /etc/cron.hourly
25 5     * * *   root    test -x /usr/sbin/anacron || run-parts
--report /etc/cron.daily
47 6    * * 7   root    test -x /usr/sbin/anacron || run-parts
--report /etc/cron.weekly
52 6    1 * *   root    test -x /usr/sbin/anacron || run-parts
--report /etc/cron.monthly

I tried changing the time on the cron.daily line to an hour earlier
(it was at hour 6), but when I came in today updatedb was chugging
along.  Experience says it should have stopped had it started an hour
earlier.  I may be repeating the obvious, but what I gather from your
post is I need to change the the file /etc/cron.d/anacron so that
anacron starts an hour ealier.

~>more /etc/cron.d/anacron
# /etc/cron.d/anacron: crontab entries for the anacron package

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

30 7    * * *   root    test -x /etc/init.d/anacron &&
/usr/sbin/invoke-rc.d anacron start >/dev/null

-----------
E.g., change that to 6 from 7, right?
