How does the "time limit (hours)" setting in Scheduled Task work?

[TheDreadPirate]

If a task takes too long to complete this setting will kill the job after the configured amount of time. Some tasks, like creating trickplays, can take many hours to complete when you add a lot of content. Audio normalization can also take a long time. And both of these examples can use a lot of CPU power. If you have a jellyfin server with limited compute power these two jobs could affect the usability of Jellyfin.

So to account for your limited CPU resources you want these jobs to run at 1 am when no one is using the system. But you want to kill the job after 5 hours (6am) when you/your users wake up and may start using Jellyfin.
