When requested to generate a UTC date in the ISO 8601 format with a time component included, an incorrect zone offset suffix is used. When ran as "date --utc -Iseconds" (or hours/minutes), a formatted value is generated which includes "UTC" as the timezone suffix which is non-compliant with the standard as a timezone designator. Either of a "Z" or "+00:00" suffix would work. Instead of the incorrect: 2020-08-28T23:46:55UTC Should generate one of the correct values as: 2020-08-28T23:46:55Z 2020-08-28T23:46:55+00:00
Fixed in git
