Timers

Meteor uses global environment variables to keep track of things like the current request’s user. To make sure these variables have the right values, you need to use Meteor.setTimeout instead of setTimeout and Meteor.setInterval instead of setInterval.

These functions work just like their native JavaScript equivalents. If you call the native function, you’ll get an error stating that Meteor code must always run within a Fiber, and advising to use Meteor.bindEnvironment.
