似乎ECMAScript应该更具体地用于边缘情况；目前is说无效的日期格式取决于实现，对吗？

根据ES5规范，将仅适用于有效日期。其他任何东西都依赖于实现（实际上，IE<9不适用于标准ISO日期，它需要一个“/”分隔符）。所以，如果你给它一个无效的日期（比如2012-11-31），你可以得到从2012-12-01到错误的任何信息

在您的测试中：

2012-12-31T23:59:60.000Z

虽然可能不像你期望的那样，但应该可以。用60秒表示闰秒，这并不等同于24:00:00，只有Safari似乎能做到这一点

此外：

应该可以，它表示2012年4月4日午夜，所以Firefox在那里出错了

ES5实现应该支持的格式在中

哦，您可能还应该测试“T”的省略（因为在某些情况下它是可选的，我认为包括浏览器）和不同的时区，例如：

2012-04-03 23:50:00+10:00
2012-04-03 23:50:00-04:15
2012-04-03 23:50:00+10
20120403T235000+1000

---

YYYYDDD和yyywwd格式也是如此，尽管不需要实现来支持它们。

看来，ES5应该更具体地表示无效dates@4esn0k-这取决于你所说的无效日期。

新日期（2012,1,30）

的结果等同于2012-02-30，并生成2012年3月1日的日期对象。

Date.parse（'2012-02-30'）

也应该这样做吗？这就是我建议手动解析日期的一个原因，这是唯一能确切知道在所有浏览器中如何处理日期的方法。另一个原因是使用中的浏览器不符合ES5的最低要求，因此即使是有效的ISO8601日期字符串也不安全。
