In SQL Server, there is the TimeStamp type, when should I use it or not instead of simply DateTime? 在SQL Server中，存在TimeStamp类型，何时应该使用它而不是简单地使用DateTime？

What is use for TimeStamp? 时间戳记有什么用？ I've heard it is to guarantee that the datetime won't be changed, like a stamp. 我听说这是要保证日期时间不会改变，就像盖章一样。 Is it? 是吗？
