Translation support

[shield-9]

If this element supports translation, it would be great!

Example:
<time datetime="2015-02-23T09:51:57Z" is="relative-time" lang="ja-jp">Feb 23, 2015</time>

Our team would be willing to put together a PR on this. @josh @dgraham any preference on how this gets implemented?

@shield-9 @nickbuddendotcom I have a separate project https://github.com/chemerisuk/better-time-element that solves similar problem and has an ability to translate displayed values. It does not rely on custom element polyfills though but uses different tricks to work on future elements as well. At present it supports only time[is=local-time] but I'm planning to add more custom elements soon.

Hi everyone! I'm trying to add l16n to this package and have some difficulties. https://github.com/ZakharDay/time-elements/tree/l16n

1. Most tests are failing and I can't resolve the issue. Two biggest problems that I can't figure out:

constructor create local-time from constructor:
undefined is not a constructor (evaluating 'new window.LocalTimeElement()')

constructor create relative-time from constructor:
undefined is not a constructor (evaluating 'new window.RelativeTimeElement()')

2. Next strange thing is when I clone my fork, change branch to l16n and then run make everything is great. But if I do npm install with link to my GitHub tarball this next two things happen.

2.1 In app where I use this package as dependency I see:

Module not found: Error: Cannot resolve module 'time-elements'

I fount that it's because I've installed it not from npm but from GitHub.

2.2 I tried to run make in node_modules/time-elements folder in my project and got this:

node_modules/.bin/rollup -c

I'll be glad for any help.

Hey all! The direction we're planning to take here is to lean on the new Intl.RelativeTimeFormat API for internationalization #104. Thanks!
