Tweaking cPanel Servers for maintenance cronjob times

Hi guys

We use cloudlinux cpanel servers for shared hosting.

Now I was looking at crons today and thought I'd clear out old ones and start tweaking times and workout and manage the times they run better.

Now a question.

I have tons of tasks in crontab -e which I assume is completely seperated to anacron times.

anacron times as per below:

/etc/anacrontab


# /etc/anacrontab: configuration file for anacron

# See anacron(8) and anacrontab(5) for details.

SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# the maximal random delay added to the base delay of the jobs
RANDOM_DELAY=45
# the jobs will be started during the following hours only
START_HOURS_RANGE=3-22

#period in days delay in minutes job-identifier command
1 5 cron.daily nice run-parts /etc/cron.daily
7 25 cron.weekly nice run-parts /etc/cron.weekly
monthly 45 cron.monthly nice run-parts /etc/cron.monthly


I I set the START_HOURS_RANGE to say to between non-office hours like 18-05 do you guys forsee any problems with any important cronjobs?
