You can configure "Time Settings and Warnings".
These settings are used to control functionality related to time punch approval and payroll transfer. It also creates a red fram around the punch in the schedule view when the warning is fullfilled.
You'll find the time settings page under Account settings > Templates in the menu on the left-hand side.
You'll see a grey text under each functionality that describes what the setting does. To activate/inactivate a setting, just check or uncheck the box under the activate column and it saves automatically.
