[TimeController/DataSynchronizer] Wrong end data after dynamic adding DataSource

[mdhsl]

After DataSynchronizer initialization, adding dataSource manually gives wrong endData to 2055 while startTime is correct.
It might be an issue into DataSynchronizer or/and TimeController:
way to reproduce

          const opts = {
            endpointUrl: 'api.georobotix.io/ogc/t18/api',
            resource: '/datastreams/khv081o7hpma2/observations',
            tls: true,
            startTime: '2023-06-06T14:01:12Z',
            endTime: '2023-06-06T22:53:14Z',
            mode: Mode.REPLAY,
            responseFormat: 'application/swe+binary',
            prefetchBatchSize: 250
          };
          const sweApiFetch = new SweApiFetch(opts);
          this.dataSynchronizer.addDataSource(sweApiFetch);
