Javascript JSON日期时间php对象

我向json发送一个json datetime对象，如何将其转换为datetime JS对象

PHP返回：

"date": {
  "lastErrors": {
     "warning_count":0,
     "warnings":[],
     "error_count":0,
     "errors":[]
  },
  "timezone": {
    "name":"Europe\/Warsaw",
    "location": {
      "country_code":"PL",
      "latitude":52.25,
      "longitude":21,
      "comments":""
    }
  },
  "offset":7200,
  "timestamp":1399413600
}

我需要在JavaScript中花费数小时和数分钟来轻松总结和显示。

使用unix时间戳从JSON转换为Datetime对象

s = '{"date":{"lastErrors":{"warning_count":0,"warnings":[],"error_count":0,"errors":[]},"timezone":{"name":"Europe\/Warsaw","location":{"country_code":"PL","latitude":52.25,"longitude":21,"comments":""}},"offset":7200,"timestamp":1399413600}}'
new Date(JSON.parse(s).date.timestamp * 1000)
