Change the Start Time Field in time aware layers

IsraAlhamood — Wed, 30 Mar 2016 15:09:02 GMT

Hello everyone,

I implemented a simple map viewer for time aware layers. it has a time slider.

I'm trying to change the start time field to another date field in the map layer.

How can I do that?

Time Info:

Start Time Field: WB_SPUD_DT

End Time Field: null

Track ID Field:

null

[1935/01/01 00:00:00 UTC, 2016/01/01 00:00:00 UTC]

N/A

Time Interval: 5

Time Interval Units: esriTimeUnitsYears

Has

Live Data: false

Use Time: true

Time Data Cumulative: false

Time Offset:

null

(null)

Isra,

Here is how to define the the start time:

          map = new Map("mapDiv", {
            basemap: "oceans",
            center: [-100, 40],
            zoom: 4
          });


          // feature service with U2 concerts from 1980 - 2011
          var featuresUrl = "https://services.arcgis.com/V6ZHFr6zdgNZuVG0/ArcGIS/rest/services/U2/FeatureServer/0";

            outFields: ["*"]
          });
          console.info(layer.timeInfo);  //This one will be undefined.
          layer.setUseMapTime(true);


          var layerUpdateEnd = layer.on("update-end", function() {
            console.info(layer.timeInfo); //This one will have an actual value because the layer is loaded.
            layerUpdateEnd.remove();
            var timeExtent = new TimeExtent();
            timeExtent.startTime = new Date("1/1/1989 UTC");
            map.setTimeExtent(timeExtent);
            domConstruct.destroy("loading");

          map.addLayer(layer);

But can I change the field itself

I meant this one

Start Time Field: WB_SPUD_DT

Can I change it to another Date type field? Or it's not possible?

Isra,

For that you will have to edit the actual mxd that the service is coming from.
