Displaying time based weather radar with Map Service

I'm using the NOAA NowCOAST ArcGIS web service to overlay the latest weather radar on version 4.13 of a JavaScript ESRI Map like this:

weatherOverlay = new MapImageLayer({
            url: "https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer/",
            title: "Weather Radar Layer",
            opacity: .7
        });

This correctly displays the most current version of the radar on my map. However, I'd like to be able to call the service to obtain historical radar as well (the previous hour every few minutes). Using this web service, how do I pass parameters in order to obtain historical renderings of the radar?
