GeoServer GetFeatureInfo with time range

Question

I've been building a WMS service for time series data following this tutorial:

http://docs.geoserver.org/latest/en/user/tutorials/imagemosaic_timeseries/imagemosaic_timeseries.html

Everything is fine and my GetMap function work well and all the maps are loaded according to their data. The problem is when I want to use the GetFeatureInfo function. If I use it to retrieve the feature value of a point for a single date it works well, but if I try to add the time range parameter I only get the feature info of the starting date.

I use it in this way: http://localhost/geoserver/cite/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&FORMAT=image%2Fjpeg&TRANSPARENT=TRUE&QUERY_LAYERS=cite%3A9_S_int&STYLES=ocean&LAYERS=cite%3A9_S_int&INFO_FORMAT=application%2Fjson&FEATURE_COUNT=50&I=50&J=50&CRS=EPSG%3A4326&WIDTH=101&HEIGHT=101&BBOX=-77.27783203125%2C-46.5380859375%2C-72.83935546875%2C-42.099609375&TIME=2018-08-09/2018-08-11&

I've always used the time range in this way for all WMS service I used. Now that I'm trying to build my own WMS service I get this problem. I've enabled the time dimension setting the presentation value to List.

Here in the following the layer properties retrieved with GetCapabilities:

                </Style>

Are there other properties I should check to enable the time range capability?

ncWMS is an extension that will allow you do do what you are asking for.

You need to incall ncWMS https://docs.geoserver.org/latest/en/user/community/ncwms/index.html It is only available as a nightly build extension (ie its not officially supported) from https://build.geoserver.org/geoserver/2.18.x/community-latest/

The differences fom GetFeatureInfo are

1. REQUEST=GetFeatureInfo -> REQUEST=GetTimeSeries
2. QUERY_LAYERS={layer-group}&STYLES&LAYERS={layer-group} -> QUERY_LAYERS={imagemosaic-name}&STYLES&LAYERS={imagemosaic-name}
3. TIME=2021-05-26T18:00:00.000Z/2021-05-27T20:00:00.000Z
