Given a pair of datetime.date or datetime.datetime objects, returns a 2-tuple of tz-aware UTC datetimes spanning the same interval. For datetime.date objects, the returned interval starts at 00:00:00.0 on the first date and ends at 00:00:00.0 on the second. Naive datetimes are upgraded to UTC. Timezone-aware datetimes are normalized to the UTC tzdata.

Accepts both a single date(time) or a full interval using either start/end or start/duration notation, with the following behavior: - Intervals are defined as inclusive start, exclusive end - Single datetimes are translated into the interval spanning the largest resolution not specified in the input value, up to the day. - The smallest accepted resolution is 1 second. - All timezones are accepted as values; returned datetimes are localized to UTC. Naive inputs and date inputs will are assumed UTC.
