根据用户的时区，有人可以帮我打印数据吗？我们有一个场景，用户将通过时区，并根据该值返回。我找到了根据用户传递时区修改日期参数的方法，并从数据库中获取结果。但之后我应该如何在时区中写入数据。我是否需要将单个日期列转换为在时区上打印，或者根据时区转换一次并打印所有值。
让我告诉您，我们尝试在现有报告中实施此功能，因此我们正在寻找最少变更的流程。
请查找示例报告的源代码。

如果你看到这是接受三个参数的构建。两个日期字段和一个用户时区提示。根据提供的日期过滤器，我将这些过滤器转换为用户时区格式并将其传递给数据库。问题是在时区打印结果时。由于我的报告有三个日期时间字段，因此应根据用户时区显示结果。
我的问题是，我可以通过任何方式在报告顶部修复时区，而不是单独转换所有三个日期时间字段。如果您需要对此进行更多说明，请与我们联系。感谢
