   <pre>Retrieves a list of Operation resources contained within the specified zone.
 
 Args:
   project: string, Project ID for this request. (required)
   zone: string, Name of the zone for request. (required)
+  orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.
+
+You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.
+
+Currently, only sorting by name or creationTimestamp desc is supported.
   maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests.
   pageToken: string, Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
   filter: string, Sets a filter expression for filtering listed resources, in the form filter={expression}. Your {expression} must be in the format: field_name comparison_string literal_string.
