IE新日期(字符串)在做什么？

Question

好吧,质量保证给了我这个错误,如果一个日期有一个字符开始日期的一个月,日或年份(格式化MM/dd/yyyy),那(仅在IE中)它将解析日期但更改它.所以挖掘周围,确定它非常奇怪..

这是我在IE中讨论的一些示例代码

$("#dates").append("<li>04/30/2012 = " + new Date("04/30/2012").toString()+"</li>");
$("#dates").append("<li>a04/30/2012 = " + new Date("a04/30/2012").toString() +"</li>");
$("#dates").append("<li>b04/30/2012 = " + new Date("b04/30/2012").toString() +"</li>");
$("#dates").append("<li>c04/30/2012 = " + new Date("c04/30/2012").toString() +"</li>");
$("#dates").append("<li>d04/30/2012 = " + new Date("d04/30/2012").toString() +"</li>");
$("#dates").append("<li>e04/30/2012 = " + new Date("e04/30/2012").toString() +"</li>");
$("#dates").append("<li>04/a30/2012 = " + new Date("04/a30/2012").toString() +"</li>");
$("#dates").append("<li>04/b30/2012 = " + new Date("04/b30/2012").toString() +"</li>");
$("#dates").append("<li>04/c30/2012 = " + new Date("04/c30/2012").toString() +"</li>");
$("#dates").append("<li>04/d30/2012 = " + new Date("04/d30/2012").toString() +"</li>");
$("#dates").append("<li>04/e30/2012 = " + new Date("04/e30/2012").toString() +"</li>");
$("#dates").append("<li>04/30/a2012 = " + new Date("04/30/a2012").toString() +"</li>");
$("#dates").append("<li>04/30/b2012 = " + new Date("04/30/b2012").toString() +"</li>");
$("#dates").append("<li>04/30/c2012 = " + new Date("04/30/c2012").toString() +"</li>");
$("#dates").append("<li>04/30/d2012 = " + new Date("04/30/d2012").toString() +"</li>");
$("#dates").append("<li>04/30/e2012 = " + new Date("04/30/e2012").toString() +"</li>");

这是IE的输出

有一些奇怪的小时添加的东西正在进行,除非你在格式的日期部分添加一个字符,然后它翻转年份到BC(从2012年到-2012 ???)

我们使用日期选择器,所以发生这种情况的可能性非常有限(但你​​知道QA人员是对的; - )......)那么其他人如何处理这种非常奇怪的行为呢？(仅供参考:我查了一下,但它需要一个MM/dd/yyyy日期并将其传递给浏览器日期解析器,所以没有骰子.

看起来可能它被解释为军事时区语义 AZ。
