Formatjs custom time string

I am working on ember-cli, and integrated formatjs. There are dates for example last donation made, and i am using best fit to display as '2 months ago' etc.

Now sometimes there is no donation and server sends 0000-00-00 which in JS converted to Mon Jan 01 1900 and when I format it using formatjs, it displayes me 115 years ago

I want to display it as Never
