Periodically updating scope variable with event

I'm listening to an event within my controller:

$scope.$on('time:update', function(event, args) {
  console.log('Update -> ' + args.time);
  $scope.time = args.time;
});

My view is not printing {{ time }} at all, even when devtools shows the console.logs.

What am I missing?

You are missing $scope.$apply(), as the updates are happening outside of Angular context, $scope.$apply is required.

I guess this is the most common issue people stumble upon when using angular. So anytime one sees data binding not working, calling the $apply method should be the first thing to try :)
