How to use countdown.js in meteor?

I would like to use contdown.js. There is a package for it in atmosphere “lee:countdown”, but it is outdated.

However the problem is, it has no documentation, and I can not figure out how to run even the outdated version.

I was thinking about adding countdown.js itself to my project, but I also can not figure out how to accomplish this.

Could you please help me out.

a bit late, though

import Countdown from 'meteor/lee:countdown';

Countdown.countdown( new Date() ).toString();

detailed information on this documentation

Please can you give example on start and end time with both in seconds. Thanks
