How to use the google-protobuf/google/protobuf/timestamp_pb.js.Timestamp function in google-protobuf

// so this is filter is not really needed but left here commented out,
    // as an example, if we want to filter stuff in the future:
    // Make a DATE filter:
    // min value two months in the past.
    // I.e. show the reports not older than min date
    // let date = new Date()
    //   , filter = new ReportsQuery.Filter()
    //   ;
    // date.setMonth(date.getMonth() - 2); // two month in the past
    // filter.setType(ReportsQuery.Filter.Type.DATE);
    // filter.setMinMaxDatesList([timestampFromDate(date)]);// just one means only min-date
    // reportsQuery.getFiltersMap().set('reported', filter);
    if('lastItemReported' in req.params) {
        let { lastItemReported, lastItemId, previous } = req.params
          , pagination = new ReportsQuery.Pagination()
          , reported = new Timestamp()
          ;
        reported.fromDate(new Date(lastItemReported));
        pagination.setItemReported(reported);
        pagination.setItemId(lastItemId);
        pagination.setPreviousPage(previous === 'true');
        reportsQuery.setPagination(pagination);
    }
    // that's the default, but for documentation …
    reportsQuery.setIncludeData(false);

    this._reports.query(reportsQuery)
        //translate into json for the client
        .then(reports=>reports.map(report=>{
            var result = report.toObject(false);
