Question

我们在表单中有一个特殊功能，它应该将日期和时间值转换为用户的本地时区。我了解到在xfdl版本8中已经有adjust-dateTime-to-timezone（）日期函数，所以我尝试使用它。

然而，我一直收到错误 Tue Jul 17 21:49:28 2012 0查看器：xforms-compute-exception：adjust-dateTime-to-timezone（../ utcDT）。

这是实际的源代码。

非常感谢您的帮助！提前谢谢！

adjust-dateTime-to-timezone的第一个参数必须是xs:dateTime，你在这里传递一个元素。所以相反，你会写：

adjust-dateTime-to-timezone(xs:dateTime(../utcDT))

如何在xforms中使用adjust-dateTime-to-timezone函数？
