mini returns -1m instead of 1m for some locales

[andreialecu]

So I just tried this with Romanian, and it appears that 1 minute ago returns -1m instead of just 1m.

There's the extra minus in a bunch of other styles in some places but not others. With the en locale everything is fine.

Is the minus a bug?

This is the default behavior when no custom mini.json style has been defined for a locale.
If one of those languages is your native one, send a pull request, along with a proof that it's your native language.

I could do that, but why would prepending the minus be the default behavior? Is there a good reason for it?

Besides the minus everything works fine for Romanian even without the custom mini.json.

Because it's how it is defined in Unicode CLDR data in the narrow style.

English (no minuses):

Some other language (has minuses):

I think most languages except English have minuses defined in the CLDR.

French has them too for example:
https://github.com/unicode-org/cldr-json/blob/master/cldr-json/cldr-dates-full/main/fr/dateFields.json

However, this library is supposed to return the time ago, so it's a bit inconsistent to return a minus from it.

I understand it's an upstream problem though, but it should maybe be mentioned as a caveat in the README.

#50 will fix it for romanian, but this is likely to be a problem for other languages as well.

Well, maybe.
I've added a comment in the README.
