问题：
I've got a table that collects forms submitted from our website, but for some reason, when they created the table, they didn't put a timestamp in the table.我有一个收集从我们网站提交的表格的表格，但由于某种原因，当他们创建表格时，他们没有在表格中放置时间戳。 I want it to enter the exact date and time that the record was entered.我希望它输入记录输入的确切日期和时间。
I know it's in there somewhere, but I can't seem to find how to set the default value (like in Access, you use getNow() or Now() ) but I don't know where to put it.我知道它在某处，但我似乎无法找到如何设置默认值（例如在 Access 中，您使用getNow()或Now() ）但我不知道将它放在哪里。
