fix: issue2551278 - datetime.datetime.utcnow deprecation.
We now use the timezone aware utc dates for python 3.11+.
But we have to make all the rest of the dates (datetime.min, unix
epoch date) timezon aware so we can subtract them. Also need to
marshall/unmarshall timezone aware iso formatted date strings.
