@cleder I can start working on this issue. Can you go ahead and assign this issue to me?

@cleder Created pull request for the same. Please review the PR.

Didn't include the tests cases for fastkmltime.py as I see there is a refactor issue for the same.

Another suggestion -

https://github.com/cleder/fastkml/blob/b9812da7fd4303d69a868e1c5e33029acf7af437/fastkml/kml.py#L204

I believe the above if condition is not required this will always return true.
