I'm not maintaining this any more.

Looking for maintainers here: https://github.com/timofurrer/maya/issues/197 - no luck so far.

If anyone wants to contribute this, don't hesitate :)

@fabaff I was able to reproduce the same test results with python3.11 as well. Digging down deep, the issue is arising from pendulum version. From 3.0.0a1, these tests are failing. If the dependency is downgraded to 2.1.2, the tests are not failing.

My suggestion would be understanding whether these two date formats 20161001T1430.4+05:30-2016-10-01T09:00:00.400000Z and 2016T14-2016-01-01T14:00:00Z are still valid according to iso8601 and remove from tests if they are not.

@timofurrer I am interested in maintaining the repo, even though I do not have much of experience in open source, but I do have experience in handling projects in work for last 8 years.
