delay() public static method

The delay is a minimum and approximate, accuracy is not guaranteed. Order of calls MUST be determined by which timers expire first, but timers with the same expiration time MAY be executed in any order.

public static delay ( $time, callable $callback, mixed $data = null ) : string
$callback	callable
$data	mixed	Arbitrary data given to the callback function as the `$data` parameter.
return	string	An unique identifier that can be used to cancel, enable or disable the watcher.

    public static function delay($time, callable $callback, $data = null)
    {
        $driver = self::$driver ?: self::get();
        return $driver->delay($time, $callback, $data);
    }
