 - Rust 代码中使用 `chrono::Utc::now()` 生成时间戳，统一在事务开始前创建 `let now = Utc::now();`，确保同一笔业务中各表时间一致。
 - `modify_date` 更新时同样需要在业务代码中显式传入 `Utc::now()`。
 
+#### 时区策略
+
+项目采用**数据库存 UTC、查询按东八区显示**的策略：
+- 业务层始终使用 `chrono::Utc::now()` 生成 UTC 时间写入数据库。
+- 每个服务在建立数据库连接池后，执行 `SET TIME ZONE 'Asia/Shanghai';`，确保 `TIMESTAMP WITH TIME ZONE` 字段在查询时以东八区格式返回。
+- 如需在 Rust 代码中做东八区展示转换，使用 `chrono::FixedOffset::east_opt(8 * 3600)` 处理。
+
 ### 4. 环境变量
 
 所有服务通过环境变量读取配置：
