bootstrap-datepicker: How to use specific time zone?
提问by Alex G
I created a small program to select the date using bootstrap-datepickerand write it to MySQL.
我创建了一个小程序来使用bootstrap-datepicker 选择日期并将其写入 MySQL。
The catch is that this date must be local to Europe/Berlinregardless where the user is at the moment.
问题是这个日期必须是本地的，Europe/Berlin无论用户现在在哪里。
$(....).datepicker({ startDate: 'today' });
My question is: how do I set startDateto be local to specific timezone without using server side code (PHP) or any other libraries?
我的问题是：如何startDate将本地设置为特定时区不使用服务器端代码 (PHP) 或任何其他库?
I tried using moment+ moment-timezonebut it's also showing the local browser date.
我尝试使用moment+moment-timezone但它也显示本地浏览器日期。
var todaysDate = moment().tz('Europe/Berlin').format();
$(...).datepicker({ startDate: todaysDate });
Thanks.
谢谢。

Just needed
刚需
moment.tz.setDefault("Europe/Berlin");
moment.tz.setDefault("Europe/Berlin");
After which moment generated the correct date without using tz(). Also make sure that format matches.
在那一刻之后生成了正确的日期而不使用tz(). 还要确保格式匹配。
var todaysDate = moment().format('D MMM YYYY');
$(...).datepicker({ format: 'dd M yyyy', startDate: todaysDate });

The date object will always be in Local time zone (browser based).
日期对象将始终位于本地时区（基于浏览器）。
dateObj.getTime()will give you absolute milliseconds.
dateObj.getTime()会给你绝对毫秒。
http://momentjs.com/is great library for timezone conversions.
http://momentjs.com/是很棒的时区转换库。

About how:
如何：
var newYork = moment.tz("2014-06-01 12:00", "America/New_York");
var losAngeles = newYork.clone().tz("America/Los_Angeles");
var london = newYork.clone().tz("Europe/London");
newYork.format(); // 2014-06-01T12:00:00-04:00
losAngeles.format(); // 2014-06-01T09:00:00-07:00
london.format(); // 2014-06-01T17:00:00+01:00
and
和
By default, moment parses and displays in local time.
默认情况下，时刻以本地时间解析和显示。
This is the exact code from their website. If you don't pass America/New_Yorkand just simply moment("2014-06-01 12:00")it will get local time.
这是他们网站上的确切代码。如果你没有通过America/New_York，只是简单地moment("2014-06-01 12:00")它会得到当地时间。
moment().utcOffset()function will get you utcOffset if you want to know which timezone moment interprets.
moment().utcOffset()如果您想知道哪个时区时刻解释，函数将为您提供 utcOffset 。
