How do I set the time of day for logwatch?

[Robert Moskowitz]

I found it.  The system-wide /etc/crontab:

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR 
sun,mon,tue,wed,thu,t
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed
17 *    * * *    root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *    root    test -x /usr/sbin/anacron || { cd / && 
run-parts --repo}
47 6    * * 7    root    test -x /usr/sbin/anacron || { cd / && 
run-parts --repo}
52 6    1 * *    root    test -x /usr/sbin/anacron || { cd / && 
run-parts --repo}

so on this system it is set for 6am period.  I can change that for 4am 
period...
