在Foundry中设置对象Timestamp属性报错，求正确实现方法

问题场景 #

给Foundry对象的Timestamp属性赋值时触发错误，代码写法：

object.timeProperty = {type: 'Timestamp', dateTime: '2023-08-18T09:50:21.385Z'}

错误栈信息：

r.getTime is not a function.
Error Parameters: {}

问题根源 #

你构造的自定义对象不符合Foundry Timestamp属性的要求。底层类型转换逻辑期望接收原生JavaScript Date对象，而不是你手动创建的带type和dateTime字段的对象——你的自定义对象没有getTime方法，这才触发了报错。

修复方案 #

直接传入原生Date对象即可，Foundry会自动完成内部类型转换：

• 从ISO时间字符串构建Date对象：

  object.timeProperty = new Date('2023-08-18T09:50:21.385Z');
  

• 若要设置当前时间，直接调用无参构造：

  // object.timeProperty = new Date();
