使用dataX工具同步数据发现部分date类型的字段值在目标表中发生变化

两个GP数据库之间同步表数据，json文件配置的是select * from table_name，全字段同步。完成数据同步后，发现目标表中部分数据的生日字段（字段类型为date）字段值比源表中此字段值小一天，例如，源表中字段值为1989-05-11，同步后目标表中值变为1989-05-10，但又不是表中所有数据此字段值都发生变化，请问大家是否遇到过此问题，应该怎样排查原因？

No source file, test, or entry point is named. Reproduce a DataX sync between the two GP databases using the reported select * configuration, then compare source and target date fields, including rows that do and do not change. Done means identifying the cause of the one-day shift and recording a verified fix or diagnostic conclusion.
