OpenApi Generator create models with type String instead of Date

Im using OpenApi Generator to create services and models for my angular project.

This is an example of my Json:

"uploadDate" : {
              "type" : "string",
              "description" : "Data caricamento",
              "format" : "date-time"
            },

When I generate the files uploadDate is converted to String instead of Date.

See:

     /**
     * Data caricamento
     */
    uploadDate?: string;

Is there a way to add a configuration and create models with Date as a type where format is date-time?

This is the script that I use to launch the generation:

"generate": "openapi-generator-cli generate -g typescript-angular -i openapi.json -o ./generated-sources/client"
