Changing locale at runtime does not change the locale of datepicker

[jooseplall]

Per docs I can see that it is possible to change the locale of the datepicker at runtime: constructor(dateTimeAdapter: DateTimeAdapter<any>) { dateAdapter.setLocale('ja-JP'); // change locale to Japanese }

I'm trying to use the datepicker in cooperation with ngx-translate. I have set up a language change subscription which would then set the locale of the selected language:

this.langSub = this._T.onLangChange.subscribe((lang: LangChangeEvent) => { this.dateTimeAdapter.setLocale(lang.lang); });

After the setLocale I can see, that the locale of dateTimeAdapter instance is changed, but the owlDateTimeLocale is still unchanged and the datepicker is shown in the locale of owlDateTimeLocale

DateTimeAdapter instance after changing the locale to 'et'

Trying to change the locale during runtime results in the error below.

How do I install these locals in general?

According to Angular's specification ja-JP is not a default name for the japanese locale, for that you should use it as 'ja'.
