提问by Snehal Masne
I am referring to http://momentjs.com/timezone/docs/#/using-timezones/
我指的是http://momentjs.com/timezone/docs/#/using-timezones/
In example, its given for below locations :
例如,它针对以下位置给出:
moment.tz.add([
'America/Los_Angeles|PST PDT|80 70|0101|1Lzm0 1zb0 Op0',
'America/New_York|EST EDT|50 40|0101|1Lz50 1zb0 Op0'
]);
I am not sure of IST values as its given for :
我不确定它给出的 IST 值:
{
name : 'America/Los_Angeles', // the unique identifier
abbrs : ['PDT', 'PST'], // the abbreviations
untils : [1414918800000, 1425808800000], // the timestamps in milliseconds
offsets : [420, 480] // the offsets in minutes
}
Could someone help in adding IST object to this?

The easiest way is to just use one of the files that includes time zone data from the moment-timezone home page, such as moment-timezone-2010-2020.js
or moment-timezone-all-years.js
(or the minified versions).
最简单的方法是只使用包含来自moment-timezone 主页的时区数据的文件之一,例如moment-timezone-2010-2020.js
or moment-timezone-all-years.js
(或缩小版本)。
You can however add just a single zone if you prefer. You can find the zone's packed string within the data files listed above. For India, the full zone definition is:
但是,如果您愿意,您可以只添加一个区域。您可以在上面列出的数据文件中找到区域的压缩字符串。对于印度,完整的区域定义是:
moment.tz.add("Asia/Calcutta|HMT BURT IST IST|-5R.k -6u -5u -6u|01232|-18LFR.k 1unn.k HB0 7zX0");
moment.tz.link("Asia/Calcutta|Asia/Kolkata");
You may or may not need the link, depending on what exactly you're doing.
您可能需要也可能不需要链接,具体取决于您在做什么。
Note that I assumed that by "IST" you mean India Standard Time, and not Irish Standard Time or Israel Standard Time. Those zones would have different data, of course.
请注意,我假设“IST”是指印度标准时间,而不是爱尔兰标准时间或以色列标准时间。当然,这些区域会有不同的数据。
Also, since India has been on UTC+5:30 since 1942, you may just wish to use a fixed offset - which would eliminate the need to use moment-timezone. Just use the utcOffset
function in moment. For example, both of the following will return the current time in India.
此外,由于印度自 1942 年以来一直使用 UTC+5:30,您可能只想使用固定偏移量 - 这将消除使用时刻时区的需要。只需立即使用该utcOffset
功能。例如,以下两个都将返回印度的当前时间。
moment().utcOffset("+05:30").format()
or
或者
moment().utcOffset(330).format()
