ISO 8601 does not specify the time zone alignment of calendar days. It
allows you to identify a date in the abstract without being specific about
time of day, or to explicitly describe a 24 hour period using the interval
representation.

Those are different things. A time without a UTC designator or UTC
difference is a local time in an unspecified time zone.
