我怎样才能从这个Instagram json获得created_time？

Question

我得到了这个json和created_time值显示整数格式的时间而不是时间格式,但我希望这个created_time以适当的格式.如何以正确的格式获取created_time？

"filter"=>"Normal",
"created_time"=>"1421677966",
  "link"=>"http://instagram.com/p/yCfw5sKorK/",
  "likes"=>{
    "count"=>1,
    "data"=>[
      {
        "username"=>"nikhil.thombare",
        "profile_picture"=>"https://instagramimages-a.akamaihd.net/profiles/anonymousUser.jpg",
        "id"=>"1651917721",
        "full_name"=>"Nikhil Narendra Thombare"
      }
    ]
