Turning on time-aware capability

CherryChan

Hello,

I am trying to create a time slider from a dynamic Json url but it is not going too well. I parsed through the data and manually created a feature layer through the help of the following link: Feature collection | ArcGIS API for JavaScript but can't seem to get any time information.

I have created a esriFieldTypeDate field in the layer definition, formatted the date in YYYYMMDDHHMMSS format and defined the feature layer as Featurelayer.MODE_SNAPSHOT. However when I was trying to access the feature layer's timeinfo properties, the console displayed the value as undefined.

How can I access/enable the time attributes?

Any help would be appreciated.

Thanks Robert,

Followed those steps and I'm making some progress. I have another question if you don't mind; when I invoke the featureLayer.setTimeDefinition(timeExtent);

I got the following message in the console log:

FeatureLayer: layer created by value (from a feature collection) does not support definition expressions and time definitions. Layer id = myFeatureLayer

Before I set the time definition, I did set up the feature layer like so:

		featureLayer = new FeatureLayer(featureCollection, {
		id: 'myFeatureLayer',
		mode: FeatureLayer.MODE_SNAPSHOT,
		outFields: ["*"]
		});
		var features = [];

In this case, does that mean time definition it is not supported?
