Need real world examples about two system settings

[nedcpa]

The first branch in the CAC is System Settings. I am unclear how two options in this branch are used.

Scheduler Credential Tab
- Update button
System Settings
- Remove Service Call Timeout in Minutes

Can some please:
-tell the real live example when you updated these settings?
-what are the pros/cons of updating these settings?

Thanks

Not much of an answer, but the first setting I have used a few times. Sometimes I get a message from CAC saying that the scheduler credentials are invalid and that macros won't run until it has been set, so all I do it to update them and then it works fine again, but don't ask me what causes this in the first place
