如何使用php访问json数组的特定字段

I am trying to access the json data from an API, and displaying it on the webpage for the time being. I am able to fetch the data array, but I want only 1 field in that data. Below is my code.

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'ACCEPT: application/json'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_URL,"https://www.localmed.com/providers/us_0651651651_9vg5u1r2g1tw3e5_f24c866/openings/?reasonForVisitId=us_1223_new_teethcleaning-adult");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);


curl_setopt($ch, CURLOPT_HEADER, false);
$result = curl_exec($ch);
curl_close($ch);

//$json_a=json_decode($result,true);
var_dump(json_decode($result, true));
var_dump ($result[1]['time']); 

Below are the results,

I need to get only the 'time' field. please help. I am getting error undefined index 'time'

array (size=1)
  'openings' => 
   array (size=10)
    0 => 
    array (size=4)
      'id' => string 'us_0651651651_9vg5u1r2g1tw3e5_f24c866_20160909T130000Z_67cbe00' (length=62)
      'uri' => string '/providers/us_0651651651_9vg5u1r2g1tw3e5_f24c866/openings/us_0651651651_9vg5u1r2g1tw3e5_f24c866_20160909T130000Z_67cbe00/' (length=121)
      'display' => null
