DatePicker localized in French encounters some issues between 1944 and 1981

[skulliah]

Hello,

I'm having a pretty annoying problem with the localized DatePicker in French. Between the years 1944 and 1981 included, there are twice the month of March and there is no month of February.

So for example when trying to choose August 15, 1970 we get September 15, 1970. The problem is not present on the default version in English and I just used the same code as the one provided on the French localized example on the website :

import DatePicker from 'material-ui/DatePicker';
import areIntlLocalesSupported from 'intl-locales-supported';

let DateTimeFormat;

if (areIntlLocalesSupported(['fr', 'fa-IR'])) {
  DateTimeFormat = global.Intl.DateTimeFormat;
} else {
  const IntlPolyfill = require('intl');
  DateTimeFormat = IntlPolyfill.DateTimeFormat;
  require('intl/locale-data/jsonp/fr');
  require('intl/locale-data/jsonp/fa-IR');
}

<DatePicker
      hintText="fr locale"
      DateTimeFormat={DateTimeFormat}
      okLabel="OK"
      cancelLabel="Annuler"
      locale="fr"
/>

I'm using firefox v55.0.1 [email protected] and [email protected] but the example on the website encounters the same problem.

Does this means that this won't be fixed until Datepicker port is ready?
Is there some workaround? Thank you.

@Trudko It will only be fixed if someone that uses it chooses to fix it.

@mbrookes thank you for quick answer! I might take a look at it. Just so I understand it seems that problem is only with localized datepickers. Also form our experience we weren't able to reproduce this on Linux(Ubuntu 16.04) and latest OSx. This has occurred only on Windows.
