In general, date/time display will follow the application locale. That means that for example the English-US version will display English-US date/time formats and the German version will display German date/time formats. Date/time display can be adjusted in the operating system settings as long as the language used in by the OS matches the language of the application. For example an English-US version will respect settings for any English locale, like English-United Kingdom, English-Australia or English-India. A French version will respect settings for any French locale, like France or Canada.
Further improvements are scheduled for version 56 beta.
