OBSOLETE - Please use the official moment package
Moment.js, a JavaScript date library for parsing, validating, manipulating, and formatting dates, packaged for Meteor.
For Meteor v0.9.0 and above:
meteor add mrt:moment
For Meteor versions below v0.9.0 using Meteorite/AtmosphereJS:
mrt add moment
Just like the moment docs tell you:
var oneMomentPlease = moment();
