Solved How to define $event?

So im trying to write a code that sets time to day, yes ik you can do /time set day but still. Anyways how would you define $event?

 

I don't understand?

To set time day

PHP:

use pocketmine\level\Level;

// let world be instanceof of a Level
$world = $this->getServer()->getLevelByName($worldname);
$world->setTime(Level::TIME_DAY);
