/setidletimeout suggests it is in seconds while behaviour is in minutes

The bug

When typing the command /setidletimeout it suggests the first arguments is in seconds (<seconds>) while the actual behaviour is in minutes.

Example

/setidletimeout 10

This will result in the following command feedback message: "The player idle timeout is now 10 seconds".

However, you need to be 10 minutes idle for it to kick you.
