How to avoid time zone issues with JQuery datepicker
提问by jumps4fun
I'm using datepicker in an input form, and sending the results through json to a database. I am using this line, to get the date from the datePicker:
我在输入表单中使用 datepicker，并通过 json 将结果发送到数据库。我正在使用这一行，从 datePicker 获取日期：
date = $("#datepicker").datepicker('getDate');
Now, I would expect this to return 2014-04-03T00:00:00.000Z
现在，我希望这会回来 2014-04-03T00:00:00.000Z
But in fact it returns 2014-04-02T22:00:00.000Z
但实际上它返回 2014-04-02T22:00:00.000Z
Notice the two hour difference, which unintentionally changes the day of month as well. I have no use for the hours and the smaller time units. However I do want the date to be right, without adding a dreaded +1to my code. I suspect this has something to do with time zones, but I can't seem to find a solution to it in the documentation, or other Q&A's online. Could anyone point me in the right direction? My time zone is GMT +1 if that matters.
请注意两小时的差异，这也会无意中改变月份中的某一天。我没有使用小时和较小的时间单位。但是我确实希望日期是正确的，而不是+1在我的代码中添加一个可怕的东西。我怀疑这与时区有关，但我似乎无法在文档或其他在线问答中找到解决方案。有人能指出我正确的方向吗？如果重要的话，我的时区是 GMT +1。
Thanks :)
谢谢 ：）

I solved this a while ago, but forgot to post an answer.
After retrieving date, this is how i fixed it:
我不久前解决了这个问题，但忘了发布答案。检索后date，这是我修复它的方式：
date.setMinutes(date.getMinutes() - date.getTimezoneOffset());

I could not figure out what you did there so I came up with a bit of a hackterrific solution.
我无法弄清楚你在那里做了什么，所以我想出了一个非常棒的解决方案。
I took the value of the alt field in UNIX:
我取了 UNIX 中 alt 字段的值：
$( function() {
$( "#datepicker" ).datepicker({
altField: "#alternate",
altFormat: "@",
});
It came out all sorts of weird with 3 extra 0's and a day behind my time zone. So I figured out the difference and added it on.
结果很奇怪，有 3 个额外的 0，比我的时区晚了一天。所以我找出了差异并添加了它。
var a = document.getElementById("alternate").value; // take alternative field UnixTimeStamp value
a = a.slice(0, -3); // get rid of 3 extra 0's
a = +a + +57000; // convert to Thai time
