  # this special ticket logic is needed since Zendesk archives tickets
  # after 120 days and doesn't return them via the client.tickets
  # endpoint as described here:
  # https://github.com/zammad/zammad/issues/558#issuecomment-267951351
  # the proper way is to use the 'incremental' endpoint which is not available
  # via the ruby gem yet but a pull request is pending:
  # https://github.com/zendesk/zendesk_api_client_rb/pull/287
  # the following workaround is needed to use this functionality
