您可以使用"2019-07-18T11:29:13.623245Z"运算符

  {
    "caption": "Execution time",
    "name": "ExecutionTime",
    "visible": true,
    "enabled": true,
    "path": "executionTime",
    "description": "Execution time",
    "dataType": "DateTime",
    "writable": true,
    "required": true,
    "number: "0000-00000-00000",
    "controlName": "DateTimePicker",
    "defaultValue": "2019-07-18T11:29:13.623245Z",
    "aspects": []
  },
