Time range strings with shared date were never implemented, like "2023-01-18T17:00/18:00" or "2013-01-01/07-01." This is part of the ISO8601 standard and should have been included.

This is done for the Java implementation, but Python and JavaScript implementations need this as well.

• [x] Java
• [x] Python
• [x] JavaScript

There should probably be a review of any other missing features. I'm pretty sure I've been moving stuff across, but December and January were a blur.

I need to go back and verify that the python changes are correct. I believe something is wrong with the test script, not the changes themselves, which are relatively trivial.

This was done back in April 2023.
