如何把数组对象的时间都转换为年月日时分秒

 let arr=[
      {
        id:1,
        name:'张三',
        details:[
          {
            id:2,
            time:'2022-07-28T17:03:12.000Z'
          },
          {
            id:3,
            time:'2022-07-29T17:03:12.000Z'
          }
        ]
      },
      {
        id:2,
        name:'李四',
        details:[
          {
            id:2,
            time:'2022-08-28T17:03:12.000Z'
          },
          {
