row_format改时间戳格式

In MySQL, the `row_format` option is related to how data is physically stored in tables on disk, including how datetime or timestamp columns are represented. The default row_format, such as `INNODB`, doesn't allow direct modification of timestamp formats; it stores timestamps as binary values internally.

However, you can change the display format when you query the timestamps using SQL functions like `DATE_FORMAT()` or `CONVERT_TZ()`. For example:

SELECT DATE_FORMAT(your_timestamp_column, '%Y-%m-%d %H:%i:%s') AS formatted_time FROM your_table;

This will return the timestamp in a human-readable format based on your chosen pattern. If you need to store the timestamps differently in a different format, you'd typically do that during data retrieval rather than changing the storage format itself.

If you're referring to a specific database engine (e.g., MariaDB) or non-default settings, please clarify, as some engines might offer more control over timestamp storage, but these are usually considered configuration details outside of the `row_format`.
