Windows does not report DST correctly in OS.get_datetime()

[ztc0611]

Godot version

3.4.3.stable

System information

Windows 11, Windows 10

Issue description

When running OS.get_datetime() on Windows, it appears to always return false for DST. We are currently in DST, but it returns "dst":false. This does not happen on MacOS. Due to the combined issue #37571, it makes RTC features very difficult.

Steps to reproduce

This line appears to always have this error on windows in my testing.

We are currently in DST

For other people looking to test this, remember that DST logic depends on the country – and in some countries, it doesn't apply in all states.

...And possibly not at all in the US next year if the act ending it passes

My bad, typed the post too quickly and meant to put "in my state"

...And possibly not at all in the US next year if the act ending it passes

The dream, honestly. DST is a nightmare. It would still be nice to be able to make it work correctly in the meantime.

I believe the code where this issue traces back to is here at line 291. I am going to attempt to figure out what is going wrong with the call.
