Change cronjob times

[poudenes]

Hi All,

I have some scripts running. Installed via amtm.
I checked the cron jobs and this is the list:

Is it safe to change those times? I prefer most of the scripts running at night and not at daytime.
Or is there a tool to use to manage cronjobs?

Most scripts will manage their own cron jobs one way or another. It could be different for each script you have installed. Some might let you change the days, others might not let you change anything, and some may pick random hours/minutes.

For Diversion it‘s b,2,1 for the blocking list updates. The stats are generated half an hour before that time.

The count ads and rotate jobs are hard coded, do not change them, Diversion will revert them to default if the router or Dnsmasq restarts.

So your suggest to leave it alone at all. sometimes I have ocd and want have things in control hahaha.... I have a 1Gbps so basically I won't see any difference when there is a update running on the router.
It's the feeling I want everything at night. And if it was harmless to change it then I change it. Haha

Some are jobs from scripts you installed, others ar for services the router provides, like letsencrypt. There are resons behind why they run at certain times. Also, there is order in that chaos, the beauty lies in that whenever the router reboots or restarts some services, the order will change. Cron just looks at the file, wakes up to run the command at the exact minute and goes back to sleep. I like that simple logic.
