Pull Request Overview

This PR updates the FormatDateTime test for New Zealand culture to handle macOS’s use of uppercase AM/PM by adding case-insensitive comparison.

• Updated the Assert.Equal call to include ignoreCase:true.
• Removed an ActiveIssue attribute that is no longer needed due to the improved date format handling.

Why does MacOS use uppercase? NZ culture is to lower case the am/pm.
Why has it failed just now?

Great question. No clue. However, to verify this on a mac terminal:

https://man7.org/linux/man-pages/man3/strftime.3.html (docs on %p)

Why has it failed just now?

I don't see a failure?

[JamesNK]

Ok. I don't think it's important enough to research closely. Most likely there is something weird about MacOS culture settings.

It wasn't previously run on Mac most likely. @radical just added Mac coverage

Hack but fine
