対処法

Please retrieve the following workaround:

1. Open the JSON file in ArcGIS Online Assistant. There is a section for the time slider widget.
2. Add currentTimeExtent to match the startTime for it to work as needed.

"widgets": {

   "timeSlider": {

      "properties": {

         "startTime": 1372636800000,

         "endTime": 1467331260000,

         "thumbCount": 2,

         "thumbMovingRate": 2000,

         "currentTimeExtent": [

            1372636800000,

            1372636800000

         ],

         "timeStopInterval": {

            "interval": 1,

            "units": "esriTimeUnitsYears"

         }

      }

   }

},
