Flink如何解决时区问题导致的数据偏移？

Flink如何解决时区问题导致的数据偏移？在不改变flink-table的schema生成逻辑的前提下，设定table.local-time-zone参数实际上也不会解决时间偏移的问题。另外，我们目前看下来由两个可以采取的方案：1. 在hologres中预先定义table schema，使用timestamp without tz进行时间保持；2. 保持原样，hologres使用系统默认时区（+....

Flink时区问题导致数据时间偏移怎么办？

Flink时区问题导致数据时间偏移怎么办？底层原因是因为CTAS中生成flink-table的schema中对应的时间列缺失了时区信息（使用timestamp类型），对吗？该列数据进入hologres时，如果holohologres中使用timestamp with tz 进行列定义，会在同样的时间上加上对于的时区信息，从而导致了数据时间偏移的情况发生。
