There are several Temporal Options settings available when defining Legend Entry options for a Legend Entry which will be published to a WMS Service using the WebMap Publisher Administrator command. Which temporal options are required to be set in order to perform time requests when connected to the WMS Service layer in Geospatial Portal application?
If temporal processing of a WMS Service layer is required when connected to the WMS Service in Geospatial Portal application, then the Support Nearest check box must be checked on the Temporal Options tab for the Legend Entry currently selected on the Map Content command dialog. This command is one of the WebMap Publisher Administrator commands available to define settings for individual Legend Entries. The Support Nearest option is only available for instance based data.
The Temporal Options tab is the third tab available on the Map Content Legend Entry dialog. The other two tabs are General and Display Options.
