The front end converts the timestamp into a date format

function (data) {
    
    
  var date = new Date(data)
  var Y = date.getFullYear() + '-'
  var M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-'
  var D = (date.getDate() < 10 ? '0' + date.getDate() : date.getDate()) + ' '
  var h = (date.getHours() < 10 ? '0' + date.getHours() : date.getHours()) + ':'
  var m = (date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()) + ':'
  var s = (date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds())
  return Y + M + D + h + m + s
}
