There is (used to be?) locale of "en_DK" (or English language for Denmark) that combined English month/day names with ISO8601 dates. Maybe there needs to be an "en_ISO" ("en_UN"?) locale that has: 1. Currency of "$" 2. Numbers with decimal point as "." and group separator as "," and leading zero on (absolute) values between 0 and 1 3. Day names of Monday->Sunday and the equivalent abbreviations 4. Month names of January->December and the equivalent abbreviations 5. Times in 24 hour HH:mm:ss format 6. Dates in ISO8601 yyyy-MM-dd format. 7. Timestamps in "pure" ISO so yyyy-MM-ddTHH:mm:ss[.ssss] and with a "Z" or ±HH[:mm] for timezone adjustments.
