Javascript日期问题，时区不正确 [英] Javascript Date issue, incorrect timezone

问题描述

我使用一些代码来制作2个JavaScript日期，将事件插入到日历组件。
日期以下列方式构建：

  var endDate = new Date（）; 
 var startDate = new Date（）; 
 
 startDate.setDate（startDateDay）; 
 startDate.setMonth（startDateMonth）; 
 startDate.setFullYear（startDateYear）; 
 startDate.setHours（2，0，0，0）; 
 
 endDate.setDate（endDateDay）; 
 endDate.setMonth（endDateMonth）; 
 endDate.setFullYear（endDateYear）; 
 endDate.setHours（2，0，0，0）; 
  

所以，日期是使用整数构建的。这些整数由输入决定，使用调试器可以看到正确的100％正确。
现在，病态描述了3个演练，2它正确地出现，1出现错误。

使用以下输入：

  endDateDay = 20 
 endDateMonth = 9 
 endDateYear = 2014 
  

提供以下日期对象作为结果：

  Tue Oct 20 2014 02:00:00 GMT + 0200（W. Europe Daylight Time）
  

---

使用此输入：

  endDateDay = 13 
 endDateMonth = 9 
 endDateYear = 2014 
  

提供以下日期对象作为结果：

  Tue Oct 13 2014 02:00:00 GMT + 0200（W. Europe Daylight Time）
  

---

现在使用此输入：

  endDateDay = 27 
 endDateMonth = 9 
 endDateYear = 2014 
  

提供以下日期对象作为结果：

  Mon Oct 27 2014 02:00:00 ** GMT + 0100 **（W.欧洲标准时间）
  

正如您所见，由于某些奇怪的原因，TimeZone已关闭。这在我的应用程序中给出错误，我需要找到一种方法来解决它。虽然，我找不到任何解决方案，更不用说了解为什么会发生这种情况。

I got this strange JavaScript bug that I can seem to work arround or fix.

I am using some code to make 2 JavaScript dates, to insert events into a calendar component. The dates are built the following way:

var endDate = new Date();
var startDate = new Date();

startDate.setDate(startDateDay);
startDate.setMonth(startDateMonth);
startDate.setFullYear(startDateYear);
startDate.setHours(2, 0, 0, 0);

endDate.setDate(endDateDay);
endDate.setMonth(endDateMonth);
endDate.setFullYear(endDateYear);
endDate.setHours(2, 0, 0, 0);

So, the dates are built using integers. These integers are determined by input, and using the debugger I can see 100% positive they are coming in correctly. Now, ill describe 3 walkthroughs, 2 where it goes correctly and 1 where it goes wrong.

Using the following input:

endDateDay = 20
endDateMonth = 9
endDateYear = 2014

Gives the following date object as result:

Tue Oct 20 2014 02:00:00 GMT+0200 (W. Europe Daylight Time)

---

Using this input:

endDateDay = 13
endDateMonth = 9
endDateYear = 2014

Gives the following date object as result:

Tue Oct 13 2014 02:00:00 GMT+0200 (W. Europe Daylight Time)

---

Now, using this input:

endDateDay = 27
endDateMonth = 9
endDateYear = 2014

Gives the following date object as result:

Mon Oct 27 2014 02:00:00 **GMT+0100** (W. Europe Standard Time)

As you can see, for some strange reason the TimeZone is off. This gives errors in my application, and I need to find a way to get it fixed. Though, I cannot find any solution to it, let alone understand why it is actually happening.

PS: I am using Google Chrome

解决方案

The answer was indeed the difference in the daylight savings time, which I completly oversaw. Thanks to finding this out I also found a solution to my problem.
