Feature Request: DateUtil package to augment DateTime functionality in Python

There may be multiple datetime formats (even within `ISO 8601`) that other processes operating in other languages pass to these workflows.

Notably, Javascript typically returns something like: `2020-03-24T00:47:49.8090000Z` for a datetime object.

The docs
(https://docs.python.org/3/library/datetime.html#datetime.datetime.fromisoformat)
suggest `dateutil` to gain the functionality of arbitrary `ISO 8601` datetime parsing from `dateutil.parser.isoparse`
