     *
     * As well as returning dates in ISO 8601 format, the D4H API expects query
     * parameters and body payloads to encode dates in this format.
     * encodeURIComponent is used to encode URL parameters:
     *
     * @example
     *
     *    // output -> Sat Nov 24 2018 10:22:35 GMT 0000
     *    encodeURIComponent(moment('Sat Nov 24 2018 10:22:35 GMT 0000'))
     *
     * Calling .toISOString() on a Date or Moment before this will return the
     * correct format:
     *
     * @example
     *
     *    // output -> 2018-11-24T10:19:13.535Z
     *    moment('Sat Nov 24 2018 10:22:35 GMT 0000').toISOString();
