In the Cesium sandcastle I see that there is an example of time dynamic WMTS. My question is whether time enabled WMS imagery providers are supported? Is time added as a parameter or in the UrlImageryProvider?

It looks like the WMS provider does take a time interval collection:

[https://cesium.com/docs/cesiumjs-ref-doc/WebMapServiceImageryProvider.html?classFilter=WebM#times](https://cesium.com/docs/cesiumjs-ref-doc/WebMapServiceImageryProvider.html?classFilter=WebM#times)

Does that work for you? What kind of project are you working on?

I’m trying to display weather data from a WMS. I’ve tried passing in a time interval, but I don’t see time showing up as a parameter in the image requests. I just get the same static image.

const providerInterval = new Cesium.TimeIntervalCollection.fromIso8601({  
iso8601: ‘2020-01-01T08:00:00Z/2020-03-01T00:00:00Z/PT1H’});  
const providerOptions = {  
type: ‘wms’,  
name: ‘USGS Topo’,  
category: ‘WMS’,

properties: {

},  
crs: ‘EPSG:3857’,  
times: providerInterval,  
clock: viewer.clock  
};  
const provider = new Cesium.WebMapServiceImageryProvider(providerOptions);  
viewer.imageryLayers…addImageryProvider(provider);

Your time parameter isn’t showing up because you’re missing a data callback. This is where you define what the parameter sent should be called, in this case, Time with a capital T.

Also, this looks pretty cool - is this an open/public dataset?

Thank you so much. It looks like the data callback was the key.

Yes the data is open; it’s from Iowa State University and they have other data sets here: [https://mesonet.agron.iastate.edu/ogc/](https://mesonet.agron.iastate.edu/ogc/)
