How to execute a daily xenforo background cron script that takes hours to run?

[Marcus]

I wonder how it is possible to do that in PHP as there is a runtime limit for each php script. So the script should be broken down in smaller tasks.

In admin.php?tools/rebuild the larger tasks are always broken down into smaller ones. Is it possible to use this system for background cron tasks?

That is the deferred system.

What is the script doing that it takes hours to run?
