Package: coreutils Version: 9.7-3
date command uses a comma ',' as the decimal point for `date --iso-8601=ns` output, causing parsing issues. but --rfc-3339 uses a dot '.' . console: '%' is command prompt ``` % date --iso-8601=ns 2025-10-25T15:21:22,840959700-07:00 % date --rfc-3339=ns 2025-10-25 15:21:40.295367270-07:00 ``` I read ISO8601 and RFC3339 and found no definition of decimal fraction of second. But should `date` command print the fraction number using locale format?
