from https://www.patternfly.org/v4/ux-writing/numerics https://www.patternfly.org/v4/ux-writing/numerics "When you represent the date as a numeric value or label, use MM-DD-YYYY." possibly the dumbest date format known to man. ISO 8601 for time format is eschewed, but they do go on to make a gesture towards internationalisation with: "Use a currency's ISO three-digit numeric code when writing for computerized systems or for countries that don't use Latin scripts." (That's ISO 4217 for all the standards buffs.)
