Hello,

I think that rather proves my theory. There will be a check whether to run this command or not, and if it is being run, the timestamp will be recorded. The question is now what the check looks like.

Stefan: Could you please check in the source of fcron or just simply test how it behaves?

Hello Stefan,

What happens to firewalls that do not run 24/7?

Will this job be performed after 12 hours have passed no matter how long? So let’s say I shut down a system for a day, would the job run immediately?
