Track project actual time in Project Planner

Hey a quick question i had was if anyone had experience tracking actuals on a project plan in Project Planner. For example we have the estimated time a project task might take but i don't see how to set how long it actually took other than just closing out the task. but even in the enterprise proejcts i don't see how to track actuals. 

There's nothing i can see as far as time sheets or time tracking either. Any help would be appreciated.
