  // events.
  //  You can list events that occurred up to 28 days ago. If unspecified, lists
  //  space events from the past 28 days.
  // * `end_time`: Inclusive timestamp until which space events are listed.
  //  If unspecified, lists events up to the time of the request.
  //
  // To specify a start or end time, use the equals `=` operator and format in
  // [RFC-3339](https://www.rfc-editor.org/rfc/rfc3339). To filter by both
  // `start_time` and `end_time`, use the `AND` operator.
  //
  // For example, the following queries are valid:
  //
  // ```
  // start_time="2023-08-23T19:20:33+00:00" AND
  // end_time="2023-08-23T19:21:54+00:00"
