According to ISO-8601, there can be any number of whitespace characters
between the time strings and timezone strings.
Unfortunately the spec isn't public, but here's the link anyway
https://www.iso.org/iso-8601-date-and-time-format.html.
Examples:
This is a valid ISO-8601 datetime string:
```
2012-04-23T10:20:30.400-02
```
Django's `django.utils.dateparse.parse_datetime` parses this correctly.
This is also a valid ISO-8601 datetime string:
```
2012-04-23T10:20:30.400 -02
```
Django's `django.utils.dateparse.parse_datetime` does not parse this
correctly and returns `None`,
However, `python-dateutil` parses it correctly. The difference is that
Django uses a very brittle REGEX to parse ISO-8601 datetime strings, and
python-dateutil does not.
I would recommend that Django:
1) Depend on python-dateutil
2) Inline python-dateutils' parsing functions
As far as I know there is no regex that can parse the full spec of
ISO-8601 datetime strings.
In the meantime, this is a patch to support (valid) whitespace characters
between the seconds/millseconds part and the timezone string.
