Missing / Incorrect Definition

Intl.DurationFormat is missing. It's implemented in all browsers except Firefox.

Sample Code

new Intl.DurationFormat('en-US', { style: 'long' }).format({ hours: 5, minutes: 2, seconds: 42 })
// '5 hours, 2 minutes, 42 seconds'

This feature is now also implemented in Firefox Nightly, behind a flag. So we can expect it to be available in all major browsers in the foreseeable future.
