Momentjs 两个实例，不同于Now

Question

momentjs 中为 fromNow() 创建自定义语言环境但又能够在其他地方使用标准语言环境的最佳实践是什么？

我希望能够使用普通的 fromNow （“几天前”），但也可以使用“短”的 fromNow （“1d+”）......意思是一天多以前。我让它工作了，但现在每当我使用 fromNow() 时，它总是使用“短” fromNow 版本

UI.registerHelper "momentizeFromNow", (ts) ->
  moment(ts).fromNow()

UI.registerHelper "momentizeFromNowShort", (ts) ->
  momentLocal = moment
  momentLocal.locale('en', relativeTime:
    future: "in %s"
    past:   "%s"
    s:  "now"
    m:  "1m"
    mm: "%dm+"
    h:  "1h"
    hh: "%dh+"
    d:  "1d"
    dd: "%dd+"
    w: "%dw"
    ww: "1w+"
    M:  "1w+"
    MM: "1w+"
    y:  "1w+"
    yy: "1w+"
  )
  momentLocal(ts).fromNow()

我已经尝试（不成功）使用 .clone() 函数

定义一个自定义语言环境，然后使用.locale() 来回切换或使用两个moment() 变量。

类似这样的：

moment.locale('en-cust', {
    relativeTime : {
    future: "in %s",
    past:   "%s",
    s:  "now",
    m:  "1m",
    mm: "%dm+",
    h:  "1h",
    hh: "%dh+",
    d:  "1d",
    dd: "%dd+",
    w: "%dw",
    ww: "1w+",
    M:  "1w+",
    MM: "1w+",
    y:  "1w+",
    yy: "1w+"
    }
});
//Defined custom locale as 'en-cust'

then = moment(1316116057189).locale('en');
thenCust = moment(1316116057189).locale('en-cust');
//Set variables to moments with specific locales

console.log(then.fromNow());
//4 years ago
console.log(thenCust.fromNow());
//1w+
console.log(thenCust.locale('en').fromNow());
//4 years ago -> switched locale with chaining method
console.log(then.locale('en-cust').fromNow());
//1w+ -> switched locale with chaining method
console.log(then.fromNow());
//1w+ as it is still set for 'en-cust' from previous chain
then.locale('en');
//Set it back
console.log(then.fromNow());
//4 years ago
