-### Example 6: Set collection time zone | Milvus 2.6.4+
-
-You can set a default time zone for your collection using the `collection.timezone` property. This determines how time-related data is interpreted and displayed for all operations within the collection, including data insertion, querying, and results presentation.
-
-The value of `collection.timezone` must be a valid [IANA time zone identifier](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones), such as `Asia/Shanghai`, `America/Chicago`, or `UTC`. Using an invalid or non-standard value will result in an error when modifying the collection property.

 ## Enhancing ANN Search
 
 AUTOINDEX considerably flattens the learning curve of ANN searches. However, the search results may not always be correct as the top-K increases. By reducing the search scope, improving search result relevancy, and diversifying the search results, Milvus works out the following search enhancements.
