问Momentjs不更新time .fromNow()

EN

UI.registerHelper('timeAgo', function(datetime) {
    Session.get('time');
    return moment(datetime).fromNow();
});

setInterval(function() {
    Session.set("time", new Date())
}, 60000); //Every minute

These Meteor functions run your code as a reactive computation:

Templates
Tracker.autorun
Blaze.render and Blaze.renderWithData


And the reactive data sources that can trigger changes are:

Session variables
Database queries on Collections
Meteor.status
The ready() method on a subscription handle
Meteor.user
Meteor.userId
Meteor.loggingIn



In addition, the following functions which return an object with a stop method, if called from a reactive computation, are stopped when the computation is rerun or stopped:

Tracker.autorun (nested)
Meteor.subscribe
observe() and observeChanges() on cursors
