JavaScript日期比较奇怪(JavaScript date comparison oddity)

 我有一个JavaScript日期比较的问题。 我为10月31日创建了一个Date对象，而11月1日创建了另一个Date对象，但每个getTime（）返回相同的数字，并且大于/小于运算符也将日期视为相等。 这是我的代码： 
 
d1 = new Date(2012, 10, 31, 0, 0, 0, 0);
d2 = new Date(2012, 11, 1, 0, 0, 0, 0);
document.write(d1.getTime() + "<br />");
document.write(d2.getTime() + "<br />");
document.write((d1 < d2) + "<br />");
document.write((d1 > d2) + "<br />");
 
 这里是输出： 
 
1354320000000
1354320000000
false
false
 
 相同的代码可以在其他月份结束时正常工作，它似乎只是导致问题的这两个日期。 
 
 任何帮助感谢！ 

I have an issue with JavaScript date comparison. I create a Date object for 31st Oct, and another for 1st Nov, yet getTime() for each returns the same figure, and the greater-than / less-than operators also consider the dates equal. Here is my code:
 
d1 = new Date(2012, 10, 31, 0, 0, 0, 0);
d2 = new Date(2012, 11, 1, 0, 0, 0, 0);
document.write(d1.getTime() + "<br />");
document.write(d2.getTime() + "<br />");
document.write((d1 < d2) + "<br />");
document.write((d1 > d2) + "<br />");
 
And here is the output:
 
1354320000000
1354320000000
false
false
 
The same code works fine around other month endings, it seems to be just these two dates that cause an issue.
 
Any help appreciated!
